The invention discloses a plastic insulation control cable, and the cable comprises 19 insulating wire cores which are stranded into a cable core in a three-layer mode of 1+6+12, wherein the gaps of the cable are provided with inorganic hydration filling layers in an extruding manner. The cable core is wrapped by a wrapping layer, and the exterior of the wrapping layer is provided with a metal shielding layer. The exterior of the metal shielding layer is provided with a plastic external protection layer in an extruding manner. The metal shielding layer consists of a metal wire layer and a metal band. The wrapping layer takes dealcoholization-type RTV silicone rubber as base rubber, takes melamine phosphate as self-intumescent flame retardant, takes magnesium hydroxide as fire retardant, and employs a synthetic fiber meshed net as a bearing body. A grounding system is reliable, and the cable is good in effect of external interference shielding, and is good in waterproof effect.
Description
technical field [0001] The invention relates to the field of cables, in particular to a plastic insulated control cable. Background technique [0002] Today, when cables are used more and more frequently, the cable industry has become the second largest industry in China after the automobile industry. With the rapid development of China's cable industry, the number of new enterprises has continued to increase, and the overall technical level of the industry has been greatly improved. But there are still various disadvantages. There are defects in the performance of the existing control cables for shielding external interference. [0003] With the development of high-rise buildings, the improvement of fire protection rating, and the strengthening of people's safety awareness, some buildings need to use fire-resistant cables to transmit higher voltage to the top of the building. Due to the high voltage, the traditional mica tape fire-resistant cable structure cannot meet the...
