三、使用特性 Property for Use
1．最高允许工作温度为70℃，短路时(5S)导体最高温度为160℃。
Allowed max．work temperature is 70℃，for short circuit(5s)，conductor max．temperature is 160℃．
2．电缆敷设时环境温度应不低于0℃，弯曲半径应不小于电缆外径的10倍。
While laying cable，the environmental temperature should not be less than 0℃，for bend radius，should be not less than 10
times of cable overall diameter．
注：我公司还可生产耐温等级90℃和120℃的电力电缆。
Note：Our factory can produce refractory 90℃and 120℃power cable．
四、型号及名称 Trype and Name
电缆型号如表1 For cable type and name see table 1
3.电缆参考外径及重量如表6。
3.For reference overall diameter and weight of cable,see Tables6.
4. 0.6/1.0KV成品电缆绝缘电阻常数，换算到20℃1km的电阻值不小于36.7MΩ·km。
The20℃ 1km resistance converted from 0.6/1.0KV finished cable insulation resistance should be not less than 36.7MΩ·km.
5. 成品电缆在室温下，应经受交流50HZ,3.5KV试验电压的耐压试验，试验稳定持续时间5分钟不击穿。
Under room temperature,finished cable can bear voltage test of AC 50HZ,3.5KV voltage test and will not be punctured for 5 minutes steady and sustained test.
6. 电缆敷设安装后应经直流耐压试验。
建议试验为4U0（U0为导体对地电压，本产品为0.6KV）时间为5分钟。
After being laid,cable should undergo DC voltage test.
We suggest the test be 4U0(U0 is the voltage fromthe conductor to earth.This product is 0.6KV)and time to be 5mins.
