Certification Description:Features:1) Lists of RSMX-NH anti-inflammable busbars apply to high fire fighting demand 3 phases, 4 lines or 3 phases, 5 lines, distribution system with AC 50 - 60Hz,660V below, rated current 250 - 3,150A2) It can still supply electricity under fire to assure enough time to start fire fighting equipment, release smoke and ventilate in order to reduce property loss and personnel injury3) Can apply to tall buildings, important control centers, under ground railways in this place, there are large numbers of people4) The structure characteristics and technical references:a) Uses twin layers, has a good rigidity and strong intensity when span is 3mlong, it can bear 70kg load in this condition, the deflection is less than 5mmb) Long times fire withstanding c) Lists of RSMX-NH anti-inflammable busbars can be divided into CMX1, CKX1-4 according to structure and fire retard insulation5) Uses perfect insulation, anti-inflammable material:a) The busbar will be winded by sheet mica, the mica conforms to standard JB/T5019 - 20-85 "electrical insulation mica product" and JB/T6488-1 - 3-92"Mica band"b) This Micaband has an enduring high hot mechanical property: tortuous strength ≥180MPa, dielectric strength ≥35kV/mm c) The temperature reaches 600°C, this mica still has good insulationd) According to different anti-inflammable limits, the heat insulation layer canbe different. If busbar is running for a long time, the heat insulation layer will be adopted by air. It is convenient to radiate heat. If busbar is running for a short time, it need high limit anti-inflammation. The insulation will be silica cotton. The silica cotton conforms to GB3003-82 "normal silicon acid aluminum fire" standard. The content for Al&sub2;O&sub3;+SiO&sub2; reach's 96% percent. This material can withstand 1,050°C, the high temperature is 1,250°C6) The busbar cover spray anti-inflammable material. When fire taken place, in the there or fire minutes, the cover material will being to form foam form heat insulation layer. The typical layer protects the busbar, this special material conforms to GB14907-94 standard7) In order to meet the fire proof requirement. The phase and joint separating block will consist of endured high temperature porcelain. This porcelain constant about 95% Al&sub2;O&sub3;. In the normal condition, the dielectric and mechanic property dielectric strength ≥13kV/mm volume resistance ratio >20mΩ.cm anti-bent; strength ≥250MPa. This porcelain has advantage to endure high temperature. If T=900°C the insulation resistanceis above 10mΩ. Also it has a stable character, can be used for a long time 8) Environment protection products: there is no poison gas to radiate. So it is a new generation environment protection product9) Flexible to arrange the busbar line. Flexible to set busbar outlet, every socketcan be used by different capacity plug boxes. The shell material of plug contactwill be adopted by endured high temperature porcelain10) Main technical references:a) RSMX-NH busbar's all characters conform to IEC439-1 - 2, GB7251.1 - 2-1997, JISC8364, GB9978, standerb) FKMC busbar withstand voltage 2,500V, one minc) FKMC busbar withstand strong dynamic and heat stable. Protection grade above IP54, seal structure of busbar
