Standard Specification for Ozone-Resistant Ethylene-Alkene Polymer Insulation for Wire and Cable — 3 стр.
Область применения

1.1 This specification covers an ozone-resisting cross-linked rubber insulation compound for electrical wires and cables. The rubber hydrocarbon component of this material consists substantially of ethylene-propylene copolymer (EPM) or ethylene-propylene terpolymer (EPDM).

1.2 This type of insulation is considered suitable for use on wire or cable which will be used in wet and dry locations with conductor temperatures up to 90°C during continuous operation, to 130°C during emergency overload conditions, and to 250°C during short-circuit conditions. It is considered suitable for all sizes and voltage classifications of single- and multiple-conductor power cables up to 35000 V phase-to-phase at the 100% insulation level and up to 25 000 V at the 133% insulation level as listed in Table 1D of Test Methods D470. Single-conductor cables shall have a supplementary covering over the insulation, and multiple-conductor cables shall have an overall covering.

1.3 The values stated in inch-pound units, except for temperature, are to be regarded as the standard. The values in parentheses are for informational purposes only.
