Embodiment

[0029] Example: Combine figure 1 , the combined control cable of this embodiment:

[0030] The cable core of the control cable is composed of an optical cable and a plurality of insulated control wire cores stranded, wherein the optical cable includes an optical fiber 1, a primary coating layer 2, a secondary coating layer 3, a braided reinforcement layer 4 and A polyolefin sheath layer 5 extruded on the braided reinforcing layer;

[0031] The three insulated control wire cores are each composed of a tinned annealed copper conductor 7 and a polyolefin insulation layer 8; a filling layer 6 is provided in the twisting gap between the optical cable and the insulated control wire core, and a wrapping layer is sequentially wrapped outside the cable core and the filling layer. The belt layer 9 is braided with tinned copper wire shielding layer 10 and extruded with polyolefin outer sheath 11 .

[0032] In a specific implementation, the braided reinforcement layer 4 is braided by ar...

Abstract

The invention discloses a combined control cable. The cable core of the control cable is formed by twisting an optical cable and a plurality of insulating control line cores. The optical cable comprises an optical fiber and a primary coating layer, a secondary coating layer, a knitted reinforcing layer and a polyolefin sleeve layer extruded on the knitted reinforcing layer, which are sequentially arranged on the optical fiber. Each insulating control line core comprises a tin-plated soft copper conductor and a polyolefin insulating layer. A filling layer is arranged in the twisting clearance of the optical cable and the insulating control line cores. A belting layer, a tin-plated copper wire shielding layer and a polyolefin outer sheath are respectively and sequentially wrapped, knitted and extruded outside the cable core and the filling layer. According to the combined control cable, high tenacity optical cable and the control cable are integrated in the same cable, thereby realizing simultaneous transmission of electric energy and data signals; and the combined control cable also has good flame resistance and good diameter axial direction water resistance performance.

Description

Technical field: [0001] The invention relates to a combined control cable and a preparation method thereof. Background technique: [0002] At present, the cables sold on the market include control cables, signal cables, flame-retardant cables, communication cables, etc. The main performance of these cables is single, and they cannot meet the needs of two or more performances. In some special occasions, it is not only necessary to transmit electric energy and control line equipment, but also to transmit signals. At the same time, in the event of an accident, if the cable burning requires less smoke and no harmful halogen acid substances, it is convenient The rescue of personnel also requires the cable to have waterproof performance. In the case of water accumulation in the laying site, the cable can be prevented from entering water and the normal operation of the circuit can be maintained. Therefore, higher requirements are put forward for the performance of the cable. Inve...
