Product Description

66kV High Voltage Power Cable 630mm2 500mm2 400mm2

(1)Technical Characteristics

XLPE cable with copper wire screen is much flexible for laying and installation in tunnel and pipeline, with the advantages of small size of overall diameter, large short circuit current carrying capacity and flexible cable cores. Moreover, the optical fiber cable which is inserted in the process of copper wire screen and distributed in the gap of copper wires. Optical fiber can be used as temperature-sensing element and also for communication and remote control.

(2) Major Technical Parameters (220kV and below Cable)

a. Partial Discharge Test: No detectable discharge exceeding to the declared sensitivity

    (5 pC or better) at 1.5 U0.
b. Power Frequency Voltage Test: No breakdown of the insulation or flashover at 2.5U₀

    for 30min.
c. Non-metal Sheath DC Voltage Test: No breakdown at DC voltage 25kV for 1min.
d. DC Resistance Measurement of Copper Wire Screen at 20ºC: The measured value shall

    comply with the specification of IEC 60228:2004.

2). Structure and Technical Characteristics of Intelligent XLPE Cable

(1) XLPE Cable with Copper Wire Screen

Integrated intelligent high voltage XLPE cable can online monitor the operation parameters during the operation of high voltage cable. It can online real-time monitor cable actual operation temperature and then realize online temperature measurement and control, online fault location and improve the operation load of cable system. Besides, it also can accomplish online monitoring of partial discharge, current carrying capacity and outer sheath condition. It can provide important specification judging evidence for cable safety operation and more load operation, ensure the cable safety operation, extend cable service life, develop the cable transmission capability to the deepest extent, reduce the operation cost, meet the requirement of customers' safety and economy, and then decrease the replace frequency, reach energy saving and consumption reducing, increase utilization
of transmission energy, achieve the best effect of transmission performance of XLPE cable, and have great economic benefit and social benefit.

(2) Structure Characteristic

On basis of digestion and absorption of overseas advanced technology, we define the structure of intelligent XLPE cable according to the temperature-sensing effect of distributed optical fiber temperature sensor and develop this new product based on this idea.
