Rated voltage Uo/U -0.6/1kV-

1. Long term allowable working temperature

2. Insulation performance

3. Maximum temperature during short circuit

These performances correspond toPVC insulated power cableOr cross-linked polyethylene power cables are consistent

Impedance: It has a low and uniform positive (reverse) and zero sequence working impedance, which is beneficial for improving power supply quality

Reactance: Concentric conductors have much higher reactance values than ordinary four core cables in zero sequence operation, which is beneficial for the sensitive action of short-circuit automatic protection devices and ensures the safe operation of related equipment

Combustion performance: 1. Flame retardant cables can withstand the bundled combustion test specified in GB12666.5 (IEC332-3),

2. Fire resistant cables can withstand the fire resistance characteristics test specified in GB12666.6 (IEC331)

Conductor resistance: in accordance with GB3956

Voltage resistance performance: withstand a 5-minute 3.5kV power frequency voltage test
