A flexible cable fire, fire-performance Nanyang electrical engineering, fire rating class only meets international GB12666.6A 950 ℃ 90min also meet British BS6387-1994 prescribed level Class A 650 ℃ 3h B 750 ℃ ??Class 3h C 950 ℃ 3h requires both in combustion can withstand water spray and mechanical shocks. 2. Whether single continuous length of long or multi-core cable length of its length to meet the power needs, limit the length of up to 2000m. 3, large cable cross-section up 1000mm2 single multi-core cable cross-section up to 240mm2.4, with flexible cable on the cable tray can dish, the bending radius ≥20D, D is the cable diameter. 5, burning smoke toxic, inorganic insulating material "does not burn the body," does not produce any harmful gases when burned, will not occur secondary pollution, be regarded as environmentally friendly green products. 6, section capacity is too large Nanyang electrical engineering, cable is not only big but also has a larger cross-section traffic overload. According to the cable wiring requirements are usually surface temperature ≤70 ℃? If wiring untouchable? Not when in contact with combustible materials? Cable sheath temperature up to 105 ℃. Fireproof cable overload permissible operating temperature up to 250 ℃. 7, corrosion-resistant, fire-resistant cables organic insulating sometimes need to wear a plastic pipe or iron pipe, plastic is easy to aging embrittlement Nanyang electric power engineering maintenance, easily corroded iron pipe; fireproof cables are not required to wear a jacket of copper pipe Nanyang electric power engineering and maintenance, copper Sheath good corrosion resistance. 8, no electromagnetic interference, fire and signal cables, control wires and cables laid in the same silos. Fireproof cable shielded copper jacket. Does not signal? Control wire and cable transmission of information generated interference. 9, flexible transportation and installation of fire cable including installation. Cable maintenance requirements and methods currently used in low-voltage cable accessories more than the major product categories shrinkable accessories, prefabricated accessories, cold shrink accessories. They each have the following characteristics: First, heat shrinkable materials are generally used for attachment of polyethylene, ethylene - vinyl acetate component of a variety of materials (EVA) and ethylene-propylene rubber, a blend of components. These products mainly used pipe stress handling electrical stress concentration problems. That parameter control method uses an electric field to alleviate the stress concentration. The main advantage is lightweight, easy to install, the performance is still good. Cheap. Tube is a volume resistivity of moderate stress (1010-1012Ωocm), the dielectric constant is large (20 - 25) special electrical parameters of heat shrinkable tube, forcing the use of the electrical parameters of the cable insulation shield stress fracture along evacuation into relatively uniform stress distribution pipe. This technique can only be used to 35kV cable attachment. Because stress tube voltage level is high fever and can not work reliably. The use of key technical issues are: To ensure that the electrical parameters of stress pipe must meet the above criteria specified value can only work reliably.
