Changsha cable 220kV full range of cable accessories passed the national type test
In August 2004, Changsha Cable Accessories Co., Ltd. manufactured a series of cable accessories for rated voltage 220kV XLPE insulated power cables. It passed the type test of the electrical industry electrical equipment quality inspection and testing center at one time. This test is based on the test standard GB. /Z 18890.1～18890.3--2002 Rated voltage 220kV (Um=252kV) XLPE insulated power cable and its accessories are carried out. The products tested include:
YJZWC4-127/220 outdoor terminal;
YJZWC4F127/220 composite set outdoor terminal;
YJZGG-127/220 GIS terminal;
YJJTI-127/220 straight through joint;
YJJJI-127/220 insulated joint.
All the type test items tested have passed the test, which indicates that the 220kV series cable accessories made in China have been broken, and the high-voltage cable accessories products are fully in line with international standards.
Changsha Cable Accessories Co., Ltd. also organized the network operation and pre-qualification test to further test the long-term operation reliability of the products to ensure the safety and reliability of the products. After more than one year of network operation in Wuhan High Voltage Research Institute, in 2007 8 On the 25th of the month, the company passed the test and all the tested test items were all qualified. The pre-qualification test report was obtained. This breakthrough result marks the 220kV series cable accessories made in China, which can be reliably and safely operated for a long time. The needs of the majority of users, high-voltage cable accessories products have been fully integrated with the international.
