Self-supporting insulated wire designed for transmission lines.

APPLICATION:

SIP-2 wire is designed for transmission lines (TLs), for rated voltage of up to 0.6/1 kW inclusive, as well as for line branches of OHL in air atmosphere.

SIP-4 wire is designed for TL branches at rated voltage of up to 0.6/1 kW inclusive, to the input, for installation along walls of buildings or structures

CONSTRUCTION:

Phase conductor - Stranded circular compacted aluminum conductor

Supporting conductor (for SIP-2 only) - Stranded circular compacted conductor made of aluminum alloy Insulation of conductors - Light stabilized cross linked polyethylene.

PERFORMANCE:

Allowable heating of conductors during operation shall not exceed 90°C under normal conditions and 250°C - at short circuit.

Normal section of main conductors, sq. mm

Max allowable load current, A, for self-supporting insulated cables of SIP-2 and SIP-4 types

Max allowable current of one-second short circuit, kA, for self-supporting insulated cables of SIP-2 and SIP-4 types
