Let me take you to understand this product: BHG1 high voltage cable boxes, BHG1 flameproof high voltage cable boxes BHG1 high voltage cable junction box is provided by the Franciscan 宁浩博 Mining Machinery Co., Ltd., a high pressure if you BHG1 cable boxes are interested or want to know more BHG1 high voltage cable boxes related information such as: price, model, pictures, please call us, negotiate! 13165376735 Liu BHG1 flameproof high voltage cable boxes BHG1 flameproof high voltage cable junction box junction box structure Introduction flameproof enclosure for steel structure, covered with bolts crimp form, on both sides of the power supply pins, and provided with a control line into devices. Case features three main terminals, terminal on the platen will crimp the cable head. Base for high-voltage porcelain, and has an auxiliary terminals. BHG1 flameproof high voltage cable boxes use: flameproof high voltage cable boxes (hereinafter referred to as junction boxes) for explosive gas (methane) and mine coal dust mixture, supply voltage up to 610 one thousand coal mine V, current up to 400 315 200 amps, the system rated current to 12.5KA disconnect the power supply system, connecting two rubber-sheathed cables for mining purposes. BHG1 junction box technology data mining flameproof high voltage cable: a flameproof high voltage cable boxes BHG1-400 / 10KV-2T 2 flameproof high voltage cable boxes (including 200 / 315A) BHG1-400 / 10KV-3T (including 200 / 315A) 3 flameproof high voltage cable boxes BHG1-400 / 10KV-4T (including 200 / 315A) 4 flameproof high voltage cable boxes BHG1-400 / 6KV-2T ( Containing 200 / 315A) 5 flameproof high voltage cable boxes BHG1-400 / 6KV-3T (including 200 / 315A) 6 flameproof high voltage cable boxes BHG1-400 / 6KV-4T (including 200 / 315A ) 7 flameproof high voltage cable boxes BHG1-400 / 3.3KV-2T (including 200 / 315A) 8 flameproof high voltage cable boxes BHG1-400 / 3.3KV-3T (including 200 / 315A) 9 flameproof high voltage cable boxes BHG1-400 / 3.3KV-4T (including 200 / 315A) 10 flameproof low voltage cable junction box BHG1-400 / 1140-4G (including 200 / 315A) 11 Mining separated Low-voltage cable boxes explosion BHG1-400 / 1140-4G (including 200 / 315A) 12 flameproof low voltage cable junction box BHG1-400 / 1140-4G (including 200 / 315A) BHG1 flameproof high voltage cable Use a junction box, junction box after unpacking, check for damage phenomenon, whether the missing parts. 2, the junction box should be suspended vertically in the upper or fixed on a dedicated stand roadway. 3, on both sides of the leading end of the cable to have the right amount of sag, not the cable head bearing. 4, both sides of the cable into the box, pallet required to stress its ends fixed cone. 5, both ends of the cable wires bare 30mm with a special compression nut pressing it with the terminals (with a special wrench) to ensure reliable contact, do not allow loose wire. 6, junction boxes ministries fastening bolts must be complete, regular checks by hand, if the problem must be timely manner. 7, junction boxes maintenance and migration are not charged in the situation, after which you must power off, press the "coal mine security procedures" required after discharge with a reliable means before opening the lid. 8, the junction box must be grounded in the use. 9, before the pre-cable terminal must first be pressed flanges, seals, ring set into the cable section and China Unicom, according to the high-voltage cable terminal cable terminal to handle the production process. 10, in the absence of the control line is introduced, to monitor both ends of the shield are mixed together, through the auxiliary terminals coupled together. The ground wire woven together at both ends respectively, received within the respective grounding device.
