Henan InfoQuick bridge voltage electrical equipment Co., Ltd. (www.jtqiaojia.com) is located in the Economic Development Zone of Zhengzhou, Henan Zhengzhou clouds technical Temple office, Contact: Mr. Wang distribution box, shaft cable trays, slotted cable tray, tray cable tray, Ladder type cable tray, DJ-type large span cable tray, CABLOFIL mesh cable tray, hot dip galvanized cable trays, stainless steel cable tray, aluminum cable tray, room alignment tray, FRP cable tray, CSP alloy plastic cable tray tray cable bridge sites, cable tray installation - Henan InfoQuick bridge voltage electrical equipment Co., users should understand the repair units eligibility standards, in particular the condition and repair work is directly related to the processing equipment and the quality of personnel . If the user equipment repair work themselves, they should understand the relevant regulations and standards. 1.5 The manufacturer shall provide maintenance information: a) the technical specifications; b) the use of performance and conditions of use; c) disassembly and assembly instructions; d) qualifications; e) signs; distribution box, shafts cable tray, cable tray trough , tray cable tray, Ladder type cable tray, DJ-type large span cable tray, CABLOFIL mesh cable tray, hot dip galvanized cable tray tray cable tray, stainless steel cable tray, aluminum cable tray, cable tray room to go FRP cable tray, CSP alloy plastic cable tray, cable tray installation - the mid-1980s, Henan InfoQuick bridge voltage electrical equipment Co. intensive last century, Zunyi Changzheng Electric Control Equipment Factory is representative of the insulating material covering the conductive row and then fastened to the sides. Insulation: Teflon tape, the working temperature of 200 degrees tray cable bridge model, people produce lethal poison gas (fluorine octafluoroisobutene and phosgene) when the shortcomings of pyrolysis polyester film, the presence of flammable, elongation and resistance tear poor tray cable tray market, the material brittle, easily cracked, causing cracks in the insulation layer, the occurrence of discharge, short circuit. PVC heat shrink tubing, great differences in quality, some manufacturers use cheap products, the measured reach Class B insulation. Irradiation crosslinked flame around the band (PER) is currently a good thing, working temperature of 150, good waterproof performance, flexible, wrapped more closely. Overall Disadvantages: an insulating layer may be damp, (there is a gap between the insulation layer) caused by a short circuit. Positioning the mounting position by measuring elastic line method identifies bridge to determine a good bracket fixed location, good marks. Positioning the bridge shaft installation shall be determined by the first base line hanging wire method, such as reserved holes inappropriate, should adjust, and make repair.
