79 LIVE WORKING – INSULATING ROPES
81 FOREWORD
82 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
83 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
84 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in
85 addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
86 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
87 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
88 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
89 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
90 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
91 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
92 consensus of opinion on the relevant subjects since each technical committee has representation from all
93 interested IEC National Committees.
94 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
95 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
96 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
97 misinterpretation by any end user.
98 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
99 transparently to the maximum extent possible in their national and regional publications. Any divergence between
100 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
101 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
102 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
103 services carried out by independent certification bodies.
104 6) All users should ensure that they have the latest edition of this publication.
105 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
106 members of its technical committees and IEC National Committees for any personal injury, property damage or
107 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
108 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
109 Publications.
110 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
111 indispensable for the correct application of this publication.
112 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
113 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
114 respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
115 may be required to implement this document. However, implementers are cautioned that this may not represent
116 the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC

164 INTRODUCTION
165 Insulating ropes designed and manufactured according to this document contribute to the safety of the
166 users, provided they are used by trained and qualified persons, in accordance with safe methods of
167 work and the instructions for use.
168 This document defines the required electrical properties of insulating ropes which already meet other
169 specifications relating to mechanical strength, physical and construction properties, for use as an
170 insulating rope, where the dielectric properties of the insulating rope are required or relied upon, at the
171 power frequency system voltages up to and including 800 kV RMS. The standard testing is performed
172 to reflect AC conditions.
173 Insulating ropes are needed when working in an energized environment whether utilizing direct-contact
174 live working, non-contact methods while working in electromagnetic fields (capacitive coupling) or for
175 de-energized work methods for protection from accidental energization. (i.e. lightning, switching errors,
176 equipment failures etc.) Applications for insulating ropes include but are not limited to general live
177 working methods, pulling, and stringing of conductor, bare hand methods, helicopter human external
178 cargo, safety netting, tree trimming, rescue and escape, rope access, tag lines and hand lines.
179 Natural fibres such as cotton, sisal, hemp and manilla or synthetic fibres untreated or uncoated such as
180 nylon, polyester, liquid crystal polymer and aramid may be unsuitable for this application, as are any
181 other ropes that exhibit electrical conductivity. Examples of ropes which are able to meet the
182 requirements of this document are formed from fibres that have an extruded thermoplastic jacket with
183 sealed ends or other form of coating or additives, such as wax, which enhances their dielectric and
184 hydrophobic properties.
185 The purpose of this document is to focus on the insulating ropes that are used to insulate the workers
186 from the energized circuits.
187 This document does not propose to address all the safety factors associated with the use of the
188 insulating rope. It is the responsibility of the user to establish appropriate safety practices. The end user
189 is responsible to validate the testing data and reports provided by the supplier and to ensure the
190 conformity and validation prior to choosing an insulating rope and utilizing it in service. The user is
191 responsible for accurately assessing and testing the dielectric properties of the rope in service.
192 The product covered by this document may have an impact on the environment during some or all
193 stages of its life cycle. These impacts can range from slight to significant, be of short-term or long-term,
194 and occur at the global, regional, or local level.
195 This document does not include requirements and test provisions for the manufacturers of the
196 product, or recommendations to the users of the product for environmental improvement.
197 However, all parties intervening in its design, manufacture, packaging, distribution, use,
198 maintenance, repair, reuse, recovery, and disposal are invited to take account of environmental
199 considerations.

201 LIVE WORKING – INSULATING ROPES
203 1 Scope
204 This document covers insulating ropes that are utilized during Live Working (LW) procedures
205 in contact with parts of installations operating at voltages up to and including 800 kV AC They
206 shall already meet other specifications relating to mechanical strength, physical and
207 construction properties. Insulating ropes up to a diameter of 32 mm only are given consideration
208 for the test acceptance criteria and larger diameters may require increased leakage current
209 criteria and engineering analysis for a particular application.
210 At the present time, insulating rope options include but are not limited to various styles,
211 materials, and construction, including extruded thermoplastic jacket ropes with sealed ends,
212 fibre with overlay/wax coating and additives and fibre without any additives. Extruded
213 thermoplastic jacket ropes with sealed ends are more likely to meet the acceptance criteria for
214 direct contact (Category 1) ropes.
215 This document covers in-service care and periodic testing. The arc flash properties of the
216 insulating rope are not evaluated in this document but should be given consideration.
217 An Acceptance Test may be arranged between a manufacturer and the end user in order to
218 demonstrate that the product meets the specifications and requirements of this document.

403 5.4.2 Leakage current under dry conditions – Category 1 insulating rope
404 The electrical tests under dry conditions for Category 1 insulating ropes are described in the
405 following clauses.
406 5.4.2.1 Test Set-up for both dry and wet conditions
407 The test shall be performed on three test pieces with a minimum length of 1500 mm. A voltage
408 of 100 kV RMS shall be applied across a 300 mm length of insulating rope for 1 min and the
409 leakage current during this period shall be measured (see Figure 2 for example of a test set-
410 up).

414 Figure 6 – Example of test set up to measure leakage current
415 Prior to commencing tests with the test piece, the leakage current shall be measured with no
416 test piece in the test fixture to determine the background capacitive stray currents. The
417 measured leakage current shall be less than 6 μA at 100 kV RMS applied across the electrodes
418 with a 300 mm separation. If leakage current of the test fixture exceeds 6 μA, the setup shall
419 be repaired/reconfigured before proceeding.
420 NOTE: The position of the test setup in relation to grounded walls and the high voltage test supply can influence the
421 measured leakage current. It is suggested that:
422 1. Distance between test arrangement and grounded walls:
423 Distance can be greater than 1000 mm around test arrangement without any other equipment, walls etc.
424 2. Positioning of the voltage supply (high voltage side):
425 A 90-degree angle or greater can be applied between the high voltage supply and the insulating rope.
426 Figure 3 shows suggested minimum clearances: 600 mm vertical from upper electrode to
427 insulating rope attachment point (A) and 1000 mm horizontal (appr. 2100 mm above floor).

432 5.4.2.2 Test procedure for dry conditions
433 The test piece shall be mounted in the vertical position with a distance of 1 500 mm between
434 the attachment points and tensioned at the lower attachment point with a 4,5 kg mass.
435 The electrodes shall be centred in the test section with a clearance of 300 mm between the
436 electrodes and mounted to provide a good electrical contact. Figure 1 illustrates the connection.
437 The electrodes and configuration shall be the same as those in Figure 4. Electrical contact is
438 made through clamps that fit snugly around the insulating rope. The electrodes shall be
439 mounted in a suitable non-conductive frame like Figure 4 to allow the suspension of the 300
440 mm test section between the electrodes. See Figure 5 and Figure 6 for the upper and lower
441 electrode plate and clamp details. The dies should not protrude past the bottom (Figure 5) or
442 top (Figure 6) of the plate. The lower clamp shall be isolated from the lower plate by use of an

457 electrode shall be connected to earth. The voltage shall be raised to 100 kV RMS in a 10 s to
458 20 s interval and maintained at 100 kV RMS for a period of 1 min. After 1 min, the voltage shall
459 be decreased to zero in not more than 5 s.
460 The applied voltage and leakage current shall be recorded continuously at a frequency of at
461 least once per second for the entire duration of the test and the recorded applied voltage and
462 leakage current shall be included with the test report. All test and measurement equipment shall
463 be calibrated as per the manufacturer’s specification.
464 5.4.2.3 Test acceptance criteria
465 The leakage current test under dry conditions shall be considered as passed if
466 – the measured maximum leakage current does not exceed 20 μA RMS at any time during the
467 1 min test,
468 – the leakage current is stable and not increasing at the end of the 1 min interval,
469 – during the test, the insulating rope does not initiate a flashover, and at the end of test, the
470 insulating rope does not show burn marks or other signs of damage after a visual
471 verification.
