What are the characteristics of the power cable of Zhengzhou first cable Co., Ltd. among Zhengzhou cable manufacturers

  　　  The characteristics of the power cable of Zhengzhou first cable Co
, Ltd
The specifications of power cables are different, but they all have the following characteristics and manufacturing requirements (1) the working voltage is high, so the cable is required to have excellent electrical insulation performance (2) the transmission capacity is large, so the consideration of the thermal performance of the cable is more prominent (3) since most of them are fixed and laid under various adverse environmental conditions (underground, tunnel ditch pipe, shaft slope and underwater, etc
), and require reliable operation for decades, the requirements for protective layer materials and structures are also high (4) due to the changes of power system capacity, voltage, phase number and other factors and different laying environmental conditions, there are many varieties and specifications of power cable products According to the strong current characteristics in the application of power cable, the consideration of its electrical and mechanical properties is more prominent
