[Professional] wholesale power cable manufacturer

 1. Power Cable Installation Notes 1) shall be installed parallel to the cable and keep the heat pipe 2m distance, cross should be kept 0.5m 2) cable with other pipeline parallel or cross to keep a distance of 0.5m 3) buried cable installation When installing, 1-35kv cable buried depth of not less than 0.7m 4) and below 10kv cable when installed in parallel, mutual spacing of not less than 0.1m, 10-35kv not less than 0.25m; when you cross the installation distance of not less than 0.5m 5) cable laying temperature of not less than 0 0 C, core cable bend radius> = 15 (D + d), single core cables> = 20 (D + d) (D is the cable diameter, d is the Conductor OD) 6) kv and over cable joints [1] when installing cable terminal head, stripped semiconductor electrical panel must not damage the insulation operation, should avoid marks and uneven, with the sandpaper shield ends should be smooth, if necessary, and to The graphite layer (particles) cleaned. [2] plastic insulated copper cable ends and steel armor shield must be grounded on the short line should also follow this principle, avoid Unbalanced Operation steel armor ends induced electromotive force, or even "ignition" and burn care sets and other accidents. Ground Lead To tinned copper braid and copper cables to connect ferrochrome soldering applications should not use spray type seal welded to avoid burning insulation. [3] Three-phase copper shield should be connected to the ground, respectively, pay attention to the grounding wire and steel armor shield grounding wire should be drawn separately insulated from each other, the position of the welding wire should be on the lower. 7) the basic requirements of the cable ends and middle joints: a good conductor connection; b insulation reliable, recommended radiation crosslinking heat-shrinkable plastic insulating material; c sealed; d 跔 mechanical strength, and energy... adapt to various operating conditions. 8) The cable ends must prevent the erosion of water and other corrosive materials, to prevent water trees cause insulation breakdown caused by aging. 9) You must use the cable loading crane or forklift transport ban flat, flat, shall be used to put the cable car when a large cable installation, in order to avoid the cable by external operations or for artificial drag and abrasions. 10) If for some reason can not be the cable laying, it should be stored in a dry place to prevent water and other sun exposure ends. Note: wire and cable wire and cable installation should be familiar with the performance of the installer or as a full-time technical staff, such as the matter is still not clear, ask the relevant technical department or Shanghai Pu largest cable factory technical advice. 2. Use the characteristics of the cable laying and operating conditions 1) Rated voltage 0.6 / 1kv PVC insulated power cable [1] cable conductor Working temperature: <= 70 0 C [2] short (the longest duration of no more over 5s) maximum operating temperature of the cable: After 160 0 C [3] DC withstand voltage cabling 3.5kv / 15min without breakdown. [4] laying in the air from the center of a single-core cables laid in parallel time: 185min 2 and below two times the diameter: 240min 2 and above is 90mm; b ambient temperature:. 30 0 C; c different environments.
