The outer sheath 1 is irradiation cross-linked flame-retardant polyolefin, has certain flame-retardant performance and certain wear-resistant and weather-resistant performance, and can effectively protect cables.
The flame-retardant sleeve 2 is made of high-purity aluminum silicate refractory fiber which adopts industrial alumina and high-purity silica sand or quartz sand as raw materials, and a small amount of B can be added2O3Or ZrO2The Al-containing fiber is prepared by mixing the raw materials, melting, blowing or spinning the mixture into fiber2O3About 50 mass% of Al2O3+SiO2>99 percent (mass), the maximum using temperature of 1260 ℃, and the long-term using temperature of 1100 ℃. The flame-retardant sheath 2 has a high fire-resistant temperature, and can effectively prevent the external high temperature of the cable from being transmitted to the inside even if the outer sheath 1 is damaged.
The cable shielding sleeve 3 is a tinned copper mesh sleeve, and can improve the capacity of resisting external electromagnetic interference of the cable and the capacity of radiating electromagnetic interference outwards of the system.
The inner sheath 4 is a polyvinyl chloride pipe, and has good insulating property and easy installation.
The mounting sleeve 5 is a silicon rubber rod. The silicon rubber is characterized by high-temperature stability, and although the strength of the silicon rubber at normal temperature is only half of that of natural rubber or some synthetic rubber, the silicon rubber can still keep certain flexibility, rebound resilience and surface hardness under the high-temperature environment of more than 200 ℃, and the mechanical properties are not obviously changed. Meanwhile, the silicon rubber has good weather resistance, Si-O-Si bonds in the silicon rubber are very stable to oxygen, ozone, ultraviolet rays and the like, and the silicon rubber has good weather resistance under the condition of not adding any additive. Meanwhile, the composite material has better electrical performance. The silicon rubber has excellent insulating property, and is very good in corona resistance and arc resistance.

It has the characteristics of common fiber (such as softness, high strength, etc.), can be made into various papers, tapes, ropes, felts, blankets, etc., and also has the high temperature resistance, corrosion resistance and oxidation resistance which are not possessed by common fiber, thus overcoming the brittleness of common refractory materials. Set up fire-resistant fiber filler between inner sheath 4, installation cover 5, can prevent the movement of buffer board 6 on the one hand, on the other hand can play certain heat-resistant effect, when avoiding the outside conflagration breaing out of cable, heat transfer to cable is inside, leads to the inside wire of cable to damage.
The conduit 8 is a PVC pipe and is arranged in the mounting sleeve 5, so that other wires can be conveniently mounted. Set up like this, can separate communication cable's power cord and communication electricity core, simultaneously, when a certain electric core damages, can very convenient take out, the threading is convenient during the change, need not change all electric cores.
