Xi'an Branch cable Branch cable Branch cable manufacturer where

Branch cable prefabricated branch cable is a new low-voltage power supply system widely used abroad in recent years, and can be used in the supply line have cable branch occasions. Such as high-rise buildings and ordinary residential buildings, large buildings and stadiums, standardized plant, mobile equipment and machinery, industrial furnaces, road, bridge, airport and so on. Compared with traditional cable branch connection and plug-in busbar, etc., with high reliability, easy installation, low environmental requirements, maintenance, etc., is a line with modern architecture and modern industrial facilities requirements of the cable products. Prefabricated branch cable according to user specifications and requirements of the cable length, and connector cable and trunk cable branch connector location on the trunk cable by cable manufacturers in the factory to the trunk cable (hereinafter referred to as the main cable) and a branch cable ( hereafter branch cable) and connectors must be insulated conductors bonded and post-related testing and test sent to the user. Installation of cable laying when users no longer need to carry out treatment and detection branch connector, it can directly connect the cable to the power line or connection with electric facilities. Because the branch connector is fully pre-made at the factory, so that the "prefabricated branch cable." Prefabricated branch cable connection has significant advantages reliable, waterproof, corrosion, acid mist, anti-vibration, bending radius, etc., can greatly reduce the labor intensity of line installation, shorten the construction period and reduce the project cost. Since the main cable conductor without joint, ensure the continuity, reduce points of failure, is currently the use of more plug-in busbar power distribution is a good alternative way, in most applications can be completely replaced by pluggable Busway. Pre-branch cable temperature there is a misunderstanding in the use of fire-resistant prefabricated branch cable, that since the fire-resistant cable can operate under fire, usually resistant to 200 ~ 300 ℃ temperature should not be a problem, in fact, not high temperature resistant cables. When the core temperature or ambient temperature of the cable outer sheath and the inner insulating the temperature exceeds 70 ℃ (or 90 ℃) that it will accelerate the aging of materials, once the outer sheath and the inner insulation cracks due to aging, the thin inner layer of tape wound package refractory layer is unstoppable invasion of moisture from the outside and quick breakdown. Therefore, it is subject to long-term operating temperature outer sheath and the inner dielectric material allows the use of temperature: NH-VV is 70 ℃, NH-YJV is 90 ℃ Third, the structure and performance requirements YFD-YJV prefabricated branch cable connection body YFD-YJV type prefabricated branch cable and the power cable has the following advantages compared to: a, has excellent thermal stability and aging stability, in normal (90 ℃), emergency (130 ℃), and short (250 ℃) Conditions By capable of delivering large current. So it's carrying capacity than the VV big. b, with excellent chemical resistance, such as inorganic salts, "oil", alkalis, acids and organic solvents. Can be widely used in a variety of harsh environments, anti-aging and long working life, generally about life than the VV cable than doubled. 7.1.1 .1 Engineering quality control standards of construction quality must meet the relevant requirements 00D162 "Building Electrical Construction Quality Acceptance" GB 50303, "cable line construction and acceptance" GB 50168, "prefabricated branch power cable installation." 7.1.2 prefabricated branch power cable installation must also comply with the design requirements and product technical documents.
