Utility model content
The good mechanical performance such as the utility model, in order to solve the problem of prior art, provides a kind of area coverage large, and the scope of application is wide, simple installation, compact conformation, bending and resistance to compression, the intelligent composite low-voltage cable of flame-proof environmental protection that temperature range of operation is wide.
The intelligent composite low-voltage cable of a kind of flame-proof environmental protection described in the utility model, comprises cable core, outside cable core, extrudes band, directly extrudes the comprehensive oversheath of rat-and-ant proof outward at band; Gap filled polypropylene gasket for packing after described cable core is stranded by three insulated wire cores, a neutral line and light unit and after stranded forms; Described light unit is formed by from inside to outside extruding colored optical fiber, the filling tape that blocks water, Loose tube, non-metal reinforcement member and oversheath successively.
Further improvement, described insulated wire cores is made up of center conductor and the insulating barrier be extruded in outside conductor.
Further improvement, the described neutral line is made up of neutral conductor and the neutral insulating barrier be extruded in outside conductor.
Compared with prior art, the utility model beneficial effect is:
1, area coverage is large, and the scope of application is wide, simple installation; The good mechanical performance such as power supply and communication unit unite two into one, and product has compact conformation, bending and resistance to compression, temperature range of operation is wide; Save the material of wiring, greatly reduce the cost of manual maintenance;
2, be provided with the neutral line in cable core, its effect is the unsymmetrical current by three-phase alternating current, reduces coat of metal and is heated, increase the current capacity of cable, ensure the safe handling of cable; And insulated conductor conductor ampacity should meet in normal working conditions, obvious temperature rise can not be produced, unaffected to ensure Optical Fiber Transmission performance;
3, because low-voltage composite cable includes fiber unit, be again directly enter indoor, achieve electric power transfer and the effective compound of optical communication; Usually, the core of optical fiber is fibre core and covering, and the two forms dielectric optical waveguide jointly, forms the conduction to light signal and constraint, realizes the transmission of light; Protect optical fiber, improve the mechanical strength of optical fiber and resist micro-curved intensity and reduce decay;
4, the open air cover of cable is formed by adopting environment protection, rat ant high-density flame-proof material, and have good resistance to wear and mechanical strength, resistance to environmental aging performance is more than 10 times of common material; Solve the aging cracking problem of common cable, simultaneously because adding environment protection, rat ant additive, also reaching the object of rat-and-ant proof, ensure that the useful life of this product and substantially increase the coefficient of safety of product.
