Abstract
The invention discloses a pre-fabricated branch cable. The cable comprises a main cable, a service-main cable, a connecting part and a branch sheath, wherein the main cable and the service-main cable are connected with each other through the connecting part, and the branch sheath is wrapped in the joint position of the main cable and the service-main cable. The branch cable provided by the invention has convenience in on-site construction and an excellent insulated, waterproof and fire-resistant property.
Description
Technical field
The present invention relates to the power cable field, specifically a kind of pre-branched cable.
Background technology
Along with the strong growth of Chinese national economy, various capital constructions, capital construction, the speed of development of real estate is accelerated, and is inevitable as confession backbone in various buildings, the facility with power cable.Therefore, from construction unit, designing unit, undertake the construction of unit in charge of construction all seek more advanced, that more cost effective, performance is more superior, take the useful space less, construction period is shorter for power distribution construction technology and method.Also just under such history environment condition, pre-branched cable enters China's architectural electricity stage in big strides.
And pre-branched cable as its name suggests, splits multi-cable exactly from leader cable, it is branch cable, it is characterized in that leader cable and branch cable insulating layer of conductor are provided with outer jacket outward, leader cable and branch cable connect to form one at the branch joint place by tap, guarantee its insulating properties.
A kind of pre-branched cable method of tradition is at the scene, oversheath, insulating barrier on one section leader cable of strip off, and the cable end with branch cable strip off oversheath, insulating barrier is connected on the conductor of leader cable again.With hydraulic tongs or alternate manner, connect by conductor adapting piece, seal processing with epoxy resin or other insulating material at last.
And the deficiencies in the prior art are: for above-described component on site construction method, its difficulty is large, specification requirement is high, also exists simultaneously dielectric strength to be difficult to guarantee, reliability, consistency are poor.
Summary of the invention
Technical problem to be solved by this invention provides a kind of have site operation convenience, insulation property, water resistance is good, fire resistance is good branch cable.
A kind of pre-branched cable of the present invention comprises main cable, branch cable, connector, branch's sheath, and its main cable is by the connector connection with branch cable, coats branch's sheath at main cable and branch cable branch joint place.
Described main cable is single core, multicore or coil buckling type multicore cable, and its direction of lay is left-hand, and does not have in vertical direction transition joint.
Described branch cable is single-core cable.
Described branch sheath is the insulation of polyvinyl chloride molding, and its thickness is not less than the trunk cable insulation thickness and adds the jacket thickness sum.
Beneficial effect of the present invention is:
The present invention is a kind of pre-branched cable, on the production line of specialized factory, production equipment and various particular manufacturing craft with specialty are produced and are made, the branch joint junction after completing, and leader cable, branch cable external sheath layer effectively are bonded to an integral body.Therefore, process cable branch joint with traditional job site or more advanced bus duct technology is compared, possessed plurality of advantages: 1, the dielectric strength of branch joint is significantly strengthened, and the branch joint insulation property are superior, reliability is high; 2, workmen's specification requirement condition descends; 3, site operation cycle, time shorten; 4, possess higher antidetonation, waterproof, fire resistance; 5, power supply safety, reliably, once effectively take up rate and reach 100%; 6, applied widely, description is many, the user can select the cable of all size, model, cross section, length voluntarily, arranges in pairs or groups arbitrarily as master, branch cable.
Description of drawings
Fig. 1 structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of pre-branched cable of the present invention, comprise main cable 1, branch cable 2, connector 3, branch's sheath 4, its main cable 1 is by connector 3 connections with branch cable 2, coats branch's sheath 4 at main cable 1 with branch cable 2 branch joint places.
The invention provides a kind of pre-branched cable version and implementation method; the above only is preferred implementation method of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention; can also make some improvement, these improvement also should be considered as protection scope of the present invention.
