(Specification)Standard Specification for Unused Polypropylene Rope with Special Electrical Properties
Standard Specification for Unused Polypropylene Rope with Special Electrical Properties
SCOPE
1.1 This specification covers the requirements, sizes, construction, tests, and procedures for unused polypropylene ropes for use by electrical utilities and related industries on energized lines operating at voltages higher than 1 kV.
1.2 This specification covers the minimum electrical, mechanical, and physical properties guaranteed by the manufacturer and the detailed procedures by which such properties are to be determined. The purchaser has the option to perform or have performed any of these tests in order to verify the guarantee. Claims for failure to meet the specification are subject to verification by the manufacturer.
1.3 The rope to which this specification applies is designed to be used in a clean and dry condition, on or near energized lines.
1.4 A margin of safety shall be allowed between the maximum voltage and working distances on which it is used and the test voltage and lengths at which it is tested.
1.5 It is common practice for the user of this type of equipment to prepare complete instructions and regulations to govern in detail the correct and safe use of such equipment.
1.6 The use and maintenance of this equipment is beyond the scope of this specification.
1.7 The values stated in SI units are to be regarded as the standard.
1.8 The following safety hazards caveat pertains only to the test method portion, Section 13, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

shall always be outside the test footage (see Fig. 2).
13.4.3 Electrodes:
13.4.3.1 The electrodes shall be designed to shield out the
majority of stray capacitive currents.
13.4.3.2 The electrodes shall be similar to those specified in
Specification F 711 for testing FRP rod and tube. Electrical
contact is made through washers that fit snugly around the
rope. The electrodes shall be mounted in a suitable frame to
allow the suspension of the 305 mm (12 in.) test section
between the electrodes. A4.5 kg (10 lb) weight shall be
attached to the rope to maintain good electrical contact. See
Fig. 4. For alternative electrode design, see Fig. 5.
13.4.4 Dry Test Leakage Readings—The 60 Hz voltage
shall be raised from 0 to 100 kV rms in not less than 5 nor more
than 15 s. The voltage shall be held at 100 kV rms for 5 min.
If at the end of 5 min the current is stable and has not exceeded
100 μA or flashed over, the specimen has passed the test. If at
the end of 5 min the current is not stable and does not exceed
100 μA, or flashover, the test shall continue for an additional 25
min. If at the end of that time the rope has not flashed over and
the current has stabilized at less than 100 μA, the specimen has
