Problems solved by technology

When non-flame retardant control cables burn, they will release a large amount of smoke and corrosive gases, which will damage valuable electronic instruments and equipment, seriously affect fire rescue and evacuation of on-site personnel, cause casualties and cause great secondary harm to electrical equipment to the fire itself

Embodiment

[0017] Example: figure 1 As shown, conductor 1 adopts multiple strands of soft tinned copper wires of the fifth type structure to be twisted into a conductive core. The conductor production goes through the following steps: wire drawing-annealing tinning-bundling-(re-twisting), for the conductor structure first Tow wire, 1mm 2 The maximum diameter of single wire in the following conductors is 0.21mm, 1.5-2.5mm 2 The maximum diameter of single wire in the conductor is 0.26mm, 4-6mm 2 The maximum diameter of single wire in the conductor is 0.31mm, 10mm 2 The maximum diameter of the single wire in the conductor is 0.41mm, and the cross section is 6mm 2 And above conductors, due to the large cross-section, the number of conductor single wires is too much, and they must be re-twisted after bundled wires. The mica tape + low-smoke halogen-free glass fiber tape composite tape is wrapped to form the inner mica tape refractory layer 2 and the inner tape layer 3. First, a layer of m...

Abstract

The invention discloses a low-smoke zero-halogen termite-proof rat-proof flame-retardant and fire-proof control cable. The cable is formed by twisting a plurality of insulating wire cores; a filling layer is arranged in a clearance of a cable core; each insulating wire core consists of a conductor, an internal mica tape fire-proof layer and an insulating layer from inside to outside; an internal belt layer is arranged between the internal mica tape fire-proof layer and the insulating layer; and a water-proof polyester tape, a water-proof isolating layer, an external mica tape fire-proof layer, an external belt layer, an oxygen-isolating water-proof layer and a sheath layer are sequentially arranged outside the cable core and the filling layer. The low-smoke zero-halogen termite-proof rat-proof flame-retardant and fire-proof control cable has high environment-friendly performance, high flame-retardant performance, high termite-proof and rat-proof performance, high fire-proof performance and high radial and axial water-proof performance, and during combustion, less smoke is generated and harmful halogeno-acid gas is not generated.

Description

Technical field: [0001] The invention relates to a low-smoke, halogen-free, ant-proof, waterproof, flame-retardant and fire-resistant control cable. Background technique: [0002] At present, the cables sold on the market include low-smoke and halogen-free control cables, ant-proof or rodent-proof control cables, waterproof control cables, flame-retardant control cables, fire-resistant control cables, flame-retardant and fire-resistant control cables, etc. The main safety performance of these cables is Monotonous, unable to meet the needs of two or more safety performances; light rail subways, nuclear industry, airports, stations, offshore platforms, hospitals, office buildings and other public places with relatively concentrated personnel and important areas of industrial and mining enterprises require cables to have high environmental performance. At the same time, these areas are also places where termites or rats are rampant, and the cables are required to be anti-ant an...
