(Specification)Standard Specification for Nonmetallic Semi-Conducting and Electrically Insulating Rubber Tapes
Standard Specification for Nonmetallic Semi-Conducting and Electrically Insulating Rubber Tapes
ABSTRACT
This specification covers nonmetallic semi-conducting and electrically insulating rubber tapes designed for the splicing and repair of electrical wire and cables operating at specified phase to phase voltages. The tapes, which are classified into five types (Types I, II, III, IV, and V), shall conform to physical property requirements such as tensile strength, elongation at break, dielectric strength, dissipation factor, permittivity, volume resistivity, behavior during fusion test, ozone resistance, heat exposure, and UV resistance.
SCOPE
1.1 This specification covers nonmetallic semi-conducting and electrical insulating tapes designed for the splicing and repair of electrical wire and cables operating at voltages up to 325 kV, phase to phase.
1.2 The SI values are the standard. The values stated in inch-pound units given in parentheses are for information purposes only.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

4.1 Types:
4.1.1 Type I—A low voltage rubber insulating tape designed for use on wires and cables operating up to 2000 V phase to phase
in dry locations with conductor temperatures up to 80 °C (176 °F) for continuous operation, up to 95 °C (203 °F) for emergency
overload conditions, and up to 150 °C (302 °F) for short-circuit conditions. For outdoor use, protect the tape from ozone attack
and ultraviolet radiation by the use of a suitable overwrap. Apply the tape to the wire or cable within an ambient temperature range
of − 10 and 40 °C (14 and 104 °F).
4.1.2 Type II—A medium voltage, ozone-resistant, rubber insulating tape designed for use with wires and cables operating up
to 35 000 V phase to phase in either wet or dry locations with conductor temperatures up to 90 °C (194 °F) for continuous
operation, up to 130 °C (266 °F) for emergency overload conditions, and up to 250 °C (482 °F) for short-circuit conditions when
installed in accordance with the manufacturer’s instruction. For wet or dry outdoor use, protect the tape from ultraviolet radiation
by the use of a suitable overwrap. Apply the tape to the wire or cable within an ambient temperature range of − 10 and 40 °C (14
and 104 °F).
4.1.3 Type III—A high voltage, ozone-resistant, rubber insulating tape designed for use with wires and cables operating up to
138 000 V phase to phase in either wet or dry locations with conductor temperatures up to 90 °C (194 °F) for continuous operation,
up to 130 °C (266 °F) for emergency overload conditions, and up to 250 °C (482 °F) for short-circuit conditions when installed
in accordance with the manufacturer’s instructions. This tape is suitable for wet or dry outdoor use. Apply the tape to the wire or
cable within an ambient temperature range of − 10 and 40 °C (14 and 104 °F).
