Ⅶ. Feature
1. XLPE insulated cable has good electrical and heat resistant performance.
2. Compared with oil filled cable, it has no risk of oil leakage, and cable laying will not effected by the fall.
3. It can bear long-term operating network voltage, and various over voltage encountered in the normal operating, such as over voltage by operation, by the atmosphere, by the fault.
4. It can transmit the power reliable.
5. It has good mechanical strength, bending, and corrosion, destroy flame-retardant performance.
6. It has no pollution, and has a long usage life.
Ⅷ. Working Condition
1. Max .operating temperature of the conductor: 90°C.
2. In short circuit condition (Max .continual period shall not exceed 5s), Max. temperature of the conductor shall not exceed 250°C.
3. Laying surrounding temperature 0°C.
4. Permitted bend radius of the cable: shall not less than 15 times of outer diameter of the cable for the single cable, and shall not less than 20 times of outer diameter of the cable for three core cable.
