Scope:

This product is suitable for frequency rated voltage 3.6 / kV-26 / 35kV distribution lines to handle electric energy.

Use features:

• frequency rated voltage Uo / U is 3.6 / 6KV-26 / 35KV.
• cable conductor to allow long-term maximum operating temperature is 90 ℃.
• When short circuit (the longest duration of no more than 5s) of the conductor temperature does not exceed 250 ℃.
• When the cable laying temperature should not be less than 0 ℃.
• cable bending radius: not less than three-core cable 15 times the cable diameter; single-core cable of not less than 20 times the cable diameter.

Select cable rated voltage

• rated voltage of cables should be suitable for cable system operating conditions, with Uo / U (Um) KV representation.
Uo- conductor cable designed for the rated power or frequency voltage between the metal shield;
Rated power cable designed U- frequency voltage between conductors;
Maximum 'highest system voltage' of Um- device can withstand.

• recommends the following table with the three-phase system value Uo cables:

A class system - such systems when any one phase conductor in contact with the ground or earth conductor, can be separated in 1min and systems;
Class B system - such systems include only single-phase ground fault condition of short-run, ground-fault time should not exceed 1h, but in any case, a maximum of 8h, the total annual duration of the earth fault does not exceed 125h;
C class system - does not belong to class A, class B systems.
