Description

Multicore lifts pre-branched cable

Technical field

The utility model relates to a kind of cables, and in particular to a kind of multicore lifting pre-branched cable.

Background technique

With the strong growth of Chinese national economy, the speed of various infrastructures, capital construction, development of real estate adds Fastly, it uses power cable to supply as various buildings, in facility, be the certainty of history with trunk.Therefore, from construction unit, design Unit, undertake the construction of unit in charge of construction all seek more advanced, more economical, performance is more superior, occupy the useful space more The power supply and distribution construction technology and method small, construction period is shorter.Also exactly under the conditions of such history environment, prefabricated branch Cable enters China's architectural electricity stage in big strides.1) in terms of middle-high building, prefabricated branch cable can be widely applied In the various middle and high floor buildings such as residential building, office building, office building, commerce and trade building, teaching building, Scientific Research Building, as supply and distribution Trunk cable uses；2) illuminated as airfield runway at airport, harbour, port and pier illumination, power supply in building facility and The backbone cable of illumination uses；3) it can be used as illuminalive power-supply in tunnel；It can be used as illumination and power power supply network under mine Road；4) in urban network reconstruction and construction, as the buried or aerial of trunk power cable；5) it is marked in modernization Quasi- workshop is used as trunk power cable；6) various buildings, facility, office building, large halls and guest houses or even sports equipment, Swimming pool etc. can be used as the use of trunk power cable.7) other various occasions using power cable, such as naval vessels, ship The trunk of equal electric system, can be used prefabricated branch cable.Branch cable has many advantages, such as simple installation, easy to maintain, The lifting load-bearing capacity of branch cable is required to be continuously improved.Therefore the strong lifting pre-branched cable gesture of exploitation tool load-bearing capacity exists It must go.

Utility model content

Utility model aims to solve the above-mentioned prior arts there is a problem of that load-bearing capacity is not strong, and it is more to provide one kind Core lifts pre-branched cable.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of multicore lifts pre-branched cable, packet Main push-towing rope core and branch's cable core are included, the main push-towing rope core is split up into main split's cable core and time branch's cable core, the master point by branch's head The outside of branch cable core and time branch's cable core, which is wrapped, is equipped with oversheath, and branch's head includes Y type copper sheathing and is filled in Y type copper sheathing Filling plastic sheath, three ends of Y type copper sheathing are provided with the fixing port that is spirally connected, and the main push-towing rope core is also packaged in oversheath In, the main push-towing rope core includes four conductors, and the outside of every conductor, which is wrapped, is equipped with insulating layer, and four conductors mutually abut, and four Lifting elements are provided at the center that root conductor abuts, all conductors are packaged in band；The thickness of the insulating layer with The thickness of the oversheath is identical.The utility model route realizes main line and branch line while constructing, branch in reduction system Case uses, and improves the integrality of route.Improve the load-bearing capacity of cable, mechanical property improves, and prevents cable because from great Cause to fall off.Branch's body contact resistance is minimum, is not influenced by expanding with heat and contract with cold.

Preferably, the lifting elements are mutually abutted with four conductors.

Preferably, secondary branch's cable core includes a conductor, the outside packet of conductor is equipped with insulating layer, the outside of insulating layer Packet is equipped with band, and the outside of band is oversheath.

Preferably, the insulating layer is crosslinked polyetylene insulated layer.

The substantial effect of the utility model is: the utility model route realizes main line and branch line while constructing, and subtracts Feeder pillar uses in few system, improves the integrality of route.The load-bearing capacity of cable is improved, mechanical property is improved, prevented Cable from great because causing to fall off.Branch's body contact resistance is minimum, is not influenced by expanding with heat and contract with cold.

Specific embodiment

Below by specific embodiment, and in conjunction with attached drawing, the technical solution of the utility model is made further specifically It is bright.

Embodiment 1:

A kind of multicore lifting pre-branched cable (referring to attached drawing 1 and attached drawing 2), including main push-towing rope core and branch's cable core, the master Cable core is split up into main split's cable core and time branch's cable core by branch's head, and main split's cable core and time outside of branch's cable core are equal Packet is equipped with oversheath, and branch's head includes Y type copper sheathing 6 and the filling plastic sheath being filled in Y type copper sheathing, Y type copper sheathing Three ends are provided with the fixing port that is spirally connected, and the main push-towing rope core is also packaged in oversheath, and the main push-towing rope core, which includes four, leads Body 1, the outside of every conductor, which is wrapped, is equipped with insulating layer 2, and four conductors mutually abut, and are provided at the center that four conductors abut Lifting elements 3, all conductors are packaged in band 4；The thickness of the insulating layer is identical as the thickness of the oversheath.Institute Lifting elements are stated mutually to abut with four conductors.Secondary branch's cable core includes a conductor, and the outside packet of conductor is equipped with insulating layer, The outside packet of insulating layer is equipped with band, and the outside of band is oversheath 5.The insulating layer is crosslinked polyetylene insulated layer.

The present embodiment realizes main line and branch line while constructing, and feeder pillar uses in reduction system, improves route Integrality.The load-bearing capacity of cable is improved, mechanical property improves, and prevents cable because causing to fall off from great.The contact of branch's body Resistance is minimum, is not influenced by expanding with heat and contract with cold.

Embodiment described above is a kind of preferable scheme of the utility model, is not made to the utility model any Formal limitation, there are also other variations and modifications on the premise of not exceeding the technical scheme recorded in the claims.
