And the voltageresistance layer has double medium buried layers, where an intermediate layer is arranged between them.
本发明耐压层具有双介质埋层，两介质埋层之间设置中间层。

For the electric welding machine two secondary side wiring and electrode holder, welding connection cable, its characteristic is high, low voltageresistance.
用于电焊机二次侧接线及连接电焊钳、电焊机的专用电缆，其特性是电阻大、电压低。
