Scope

1.1 This specification covers an ozone-resisting crosslinked silicone rubber insulating compound for electrical wires and cables.

1.2 This type of insulation is considered suitable for continuous operation at conductor temperatures up through 125°C for power cable applications. It is considered suitable for conductor sizes up to and including 1000 kcmil (507 mm²) at a maximum of 5000 V for both single-and-multiple-conductor cables. Minimum conductor sizes and insulation thicknesses are given in Table 1.

1.3 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in parentheses are for information only.

1.4 In many instances the insulation material cannot be tested unless it has been formed around a conductor or cable. Therefore, tests done on insulated wire or cable in this document are solely to determine the relevant property of the insulation material and not to test the insulated conductor or completed cable.
