Branch cable is the novel power supply technique replacing original bus duct system, it is compared with enclosed busbar groove, low price reduces, and economic index is high, and comprehensive benefit is obvious, and it is complete in specifications, select flexibly, branch's head, according to can the needs of distributor point of distribution system, can set branch location arbitrarily, combination in any, also solves the technical problem of bus duct blow-by, waterproof.Branch cable, as the term suggests split multi-cable exactly from leader cable, be provided with outer jacket outside its leader cable and branch cable insulating layer of conductor, leader cable and branch cable connect to form one at branch joint place by tap, ensure its insulating properties.
Traditional branch cable method is at the scene, oversheath, insulating barrier on strip off one section of leader cable, again the cable end of branch cable strip off oversheath, insulating barrier is connected on the conductor of leader cable, is connected by conductor adapting piece, finally with epoxy resin or other insulating material encapsulating process.Due to needs component on site construction method, difficulty is large, technical requirement is high, also there is dielectric strength simultaneously and is difficult to ensure, do not reach the fire resistant requirements of Code in Hazardous Special Locations, and reliability, consistency are poor, also can produce a large amount of toxic gas during insulating barrier burning, not meet national environmental protection policy requirements.
[summary of the invention]
The purpose of this utility model is to solve traditional bus duct blow-by, and the installation of existing branch cable is inconvenient, the technical barrier of poor reliability, adapt to the supporting demand of development of modern industry, design the fire prevention branch cable that a kind of energy-conserving and environment-protective, fire protecting performance are high, make that branch's head is simple, cable quality is light, quality is soft, can lay together after single core or many strandings.
To achieve these goals, a kind of fire prevention of design branch cable, comprise main heart yearn and branch line, conductor in described main heart yearn adopts that some copper wires are stranded to be formed, waterproof insulation material layer is wrapped up outside conductor, insulating layer is wrapped up successively from the inside to the outside outside many stranded conductors, flame retardant bed, metal resistance to compression tensile layer and ring protection jacket layer form main heart yearn, described insulating layer bonds aluminium foil again after adopting ceramic fiber paper back adhesive glass fabric and forms, compression is connect by C shape latch closure between main heart yearn and branch line, external sheath layer is wrapped up outside main heart yearn and branch line.
Described branch line is single-core cable or multicore cable, soaks to stand exchanging 3500V test voltage 1min after 1 hour and do not puncture.
Described ceramic fiber paper is replaced by ceramic fiber blanket or ceramic fiber cloth or ceramic fibre strip.
Described fire-retardant insulating material layer adopts mica tape or silicon rubber porcelain band, and two layers or more is wrapped outside conductor.
Described flame retardant bed adopts silicon rubber porcelain band ceramic fibre strip wrapped.
Described metal resistance to compression tensile layer adopts steel band or steel wire.
Described external sheath layer selects low-smoke halogen-free environment material.
Compared with the existing technology, its advantage is the utility model patent:
1, branch joint adopts synthetic material injection molded, and ensure that air-tightness and water proofing property, dielectric strength is significantly strengthened, and reliability is high, can be widely used in wet environment;
2, the cable molding scene that is assembled in of main heart yearn and branch line completes, and saves the working time of site operation, reduces the technical requirement condition of workmen, shortens site operation cycle, time;
4, higher antidetonation, waterproof, fire resistance is possessed;
5, power supply safety, reliably, once effectively take up rate and reach 100%;
6, applied widely, description is many, user can select the cable of all size, model, cross section, length voluntarily, arranges in pairs or groups arbitrarily as master, branch cable;
7, insulating layer after ceramic fiber paper back adhesive glass fabric, bonds aluminium foil again form, and refractory temperature is high, and thermal insulation is effective, and quality of materials is light, and quality is soft.
