Detailed Product Description: | High-voltage power cable ampacity calculation of high voltage power cables 1. General carrying capacity of copper wire carrying traffic safety wire is determined according to the allowed maximum conductor temperature, hayang high voltage power cables, cooling conditions, the Xi'an high-voltage power cables, laying conditions a. 2. Calculate the copper wire cross-sectional area of ??the use of copper wire safe loading capacity of recommended 5 ~ 8A / mm2, calculated copper wire cross-sectional area of ??the selected upper and lower range S: S == 0.125 I ~ 0.2 I (mm2) S --- - copper wire cross-sectional area (mm2) I ----- load flow (A) 3 power calculation general loads (appliances can also be used, such as lighting, refrigerators, etc.) is divided into two types, one type resistive load, Jingyang high voltage power cables, one is the inductive load. The formula for resistive load: P = UI for fluorescent load calculation formula: P = UIcosф where fluorescent load power factor cosф = 0.5. Different inductive load power factor is different. High voltage power cables types of high-voltage cable high voltage cable main types YJV cables, VV cable, YJLV cable, VLV cable. Full name YJV cable XLPE insulated PVC sheathed power cable (copper core) VV PVC insulated cable the full name of the power cable (copper core) YJLV full name XLPE insulated cables PVC jacket The full name of aluminum power cable VLV PVC insulated cable aluminum power cable due to the excellent conductivity copper conductors, high voltage power cables, more and more projects using copper core power cable as the power supply system of the main road, The application of aluminum power cable is less, especially in the high-voltage power system, choose the more copper cables. Yan'an high voltage power cables | high voltage power cable | Middle East cable, power cable provided by the Shaanxi Jin Bao Li cable Limited. Shaanxi Baoli Cable Co., Ltd. (www.jinlidl.com) (www.jinlidl.cn) in the power cable that area devoted boundless enthusiasm and passion, Middle East cable, gold power cable has been customer-centric, to create value for customers The concept of quality, service to win market, and sincerely hope to cooperate with the community to create success, to create brilliant.
