Medium voltage cable

Medium voltage cables are typically designed for voltage ranges from 6kV to 35kV, and are crucial for efficient power transmission and distribution in various environments. These cables are designed to provide reliable performance in indoor and outdoor installations, handling higher voltages than low-voltage cables, allowing for long-distance power transmission with minimal losses.

Technical specifications

According to different usage environments, the characteristic requirements mainly include flame retardancy, water resistance, cold resistance, rodent resistance, termite resistance, etc. Among them, flame retardancy is generally divided into ZA, ZB, ZC, ZD, and WDZA, WDZB, WDZC, WDZD.

Common voltage levels:

3.6/6 kV、6/6 kV、6/10 kV、8.7/10 kV、8.7/15 kV、12/20 kV、18/20 kV、18/30 kV、21/35 kV、26/35 kV。

Execution standard: GB/T 12706.1-2020

Usage characteristics:

1. Cable usage environment temperature: 0 ℃~90 ℃;

2. The maximum continuous operating temperature of the conductor is 90 ℃, and the maximum short-circuit temperature (with a maximum duration of 5 seconds) does not exceed 250 ℃;
