ProductUsage：

This product is suitable for 10KV power distribution system. For thetransmission of electricity purposes. Low smoke without flame retardantperformance is higher than the national standard of flame retardant, widelyused in airports, nuclear power plants, key water control projects, high-risebuildings, chemicals, metallurgy, petroleum, transportation and other flameretardant performance demanding places. Can withstand mechanical external forceand a certain amount of tension.

Implementation standards:

This product according to GB / T12706 "rated voltage 1kV ~ 35kVextruded insulated power cables and accessories," the standard production,but also according to user needs according to the InternationalElectrotechnical Commission recommended standards IEC, British standards,German standards and American standards.

Flame-retardant properties in line with GB / T 18380.3 (IEC 60332-3)requirements.

Usefeatures:

· Power frequency rated voltage U0 / U is 3.6 / 6kV ~ 26 / 35kV.

· Cable conductor maximum allowable working temperature: 90 ℃.

· Short circuit (the longest time does not exceed 5s) The maximumtemperature of the cable conductor does not exceed 250 ℃

· Cable laying ambient temperature should not be less than 0 ℃.

· Cable bending diameter: three-core cable is not less than 15 times thecable diameter; single-core cable is not less than 20 times the cable diameter

The ratedvoltage of cable is expressed with U₀/U(U_m), and it is aneffective value with a unit of kV. For example, U₀/U(U_m)=64/110(126).

U₀ -The rated power frequency voltage between the conductor and the shield or themetal armor, used for cable design;

U - The rated powerfrequency voltage between the conductors, used for cable design;

U_m - The maximum voltageof equipment (the maximum value of system voltage of the equipment in use).
