[0018] The waterproof flat silicone rubber cable provided by the utility model combines cables of different specifications and models together. It can not only transfer high-power electricity, but also transmit control system power and control signals. The product has a compact structure and is easy to use. The product has flame retardant, fire-resistant, high-temperature resistant properties, is safe and environmentally friendly, and meets the needs of users in different occasions.

[0019] The cable consists of 3 power line cores, 1 control cable core and 1 computer signal cable core in parallel. Tensile aramid yarns are placed between the cores and at both ends, and the outer layer is a silicone rubber sheath. Aramid yarns have a high degree of regularity, high temperature resistance, fire resistance, chemical corrosion resistance, extremely high mechanical properties and fatigue resistance, and a strength of 3 times that of steel. It can still maintain a high strength at high temperatures, so that the cable can be used in occasions with frequent bending and certain tension. The silicone rubber sheath has excellent high and low temperature resistance and can be used for a long time in the range of -60 to 250℃. It also has excellent electrical insulation properties, is resistant to ozone, weather aging, water repellent, moisture-proof, and has good physiological inertia and good bending resistance. The cable can be used in special occasions with a small bending radius, and can also be used in occasions that require bending and movement.

[0020] The power core in the cable is used to connect the power transmission of high-power equipment with a voltage of 0.6 / 1kV. The conductor uses a multi-strand tinned soft conductor to ensure the flexibility and good conductivity of the power core. The conductor is wrapped with two layers of overlapping mica tapes. Synthetic mica is selected. When the material encounters open flames, it will hardly produce harmful smoke. It has a high heat resistance level and can reach the A-level fire resistance level (950 to 1000℃). The temperature resistance is greater than 1000℃, and it has excellent fire resistance. The mica tape is an insulating layer outside the mica tape. Silicone rubber consistent with the sheath material is selected. In order to improve the fire resistance of the cable, a double layer of ceramic silicone rubber tape is wrapped outside the insulation layer. The ceramic silicone rubber tape can be burned into a ceramic shape after high temperature combustion, forming a hard ceramic armor to protect the line. The longer the ablation time, the harder the ceramic armor body, which can prevent the inner mica tape from becoming hard, brittle, and falling off after burning, and improve the performance of the cable to maintain normal operation in the event of a fire.

[0021] The control cable core in the cable is used to connect various electrical appliances, instruments and automation devices, and plays the role of transmitting various electrical signals, indicator light display, instrument indication, relay and switch equipment operation, alarm interlocking system, etc. The control cable core is the same as the power line core. The conductor is a multi-strand tinned soft conductor. The conductor is wrapped with two layers of mica tape, and then silicone rubber insulation is extruded. The insulation layer is wrapped with a double layer of ceramic silicone rubber tape. Then, multiple single-core wires are twisted into cables, wrapped tightly with polyester tape, and then a tinned wire shielding layer is woven to ensure accurate data transmission and protect the cable from electromagnetic interference. The shielding layer is extruded with a silicone rubber inner sheath to protect the control cable core.

[0022] The computer signal cable core in the cable is used for control lines and signal transmission of detection instruments and meters in automatic control systems, computer distributed control systems, and automation control systems based on electronic computers. The conductor also uses multi-strand tinned soft conductors. The insulation layer is different from the power line core and the control cable core. It uses fluoroplastic insulation. Fluoroplastic insulation can reduce signal attenuation and improve product stability. Fluoroplastic has excellent thermal stability and can maintain stable performance under high temperature conditions. It can be used normally under high temperature conditions within 200°C and can be used in relatively extreme and harsh environments. Each 2 insulated cores are twisted, wrapped with polyester tape, braided tinned wire shielding layer, and ceramic silicone rubber tape is wrapped around the shielding layer to protect the shielding layer and inner layer. It has both fire resistance and shielding performance. Then twist each pair of twisted cables, wrap with polyester tape, braid tinned wire total shielding layer, and the structure of sub-screen plus total screen further improves the anti-interference performance of the cable. The shielding layer is extruded with an inner silicone rubber sheath to protect the computer signal cable core.

[0023] The cable integrates different power lines and signal lines into one cable, and achieves electromagnetic compatibility by means of shielding and isolation. It has a compact structure and is easy to use, meeting the needs of users in different occasions.
