The insulation material of the branch cable adopts one step silane cross-linking polyvinyl, thereby having more reliable electrical property and physical characteristics; the branch which replaces original high-cost bus duct greatly reduces construction cost; the utility model has perfect power supply reliability and convenience in construction, thereby shortening construction time and lowering labor intensity; meanwhile, it is characterized by waterproof and dampproof function, being maintenance free for a long time, low requirement on construction environment, small floor space and bend radius, various specifications and varieties, flexible selection mode and random combination according to engineering requirement.
Description
Technical field
The utility model relates to a kind of power transmission cable, particularly relates to a kind of crosslinked polyetylene insulated branch cable.
Prior art
High speed development along with China's economic construction, skyscraper is rised sheer from level ground like the mushrooms after rain, power consumption in the building also increases greatly, make the distribution in the building more and more difficult, therefore, the complexity of building distribution becomes a big problem of people's growing interest and attention, and especially at construction site, the reliability of the reduction of distribution cost, the shortening of construction period and power supply becomes the consistent strong request of the investor and builder and power supply department.
Though can solve branch problem in the distribution with traditional bus duct, there are many inadequate natural endowments in bus duct: as use inconvenience, have potential safety hazard etc.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of crosslinked polyetylene insulated branch cable that can overcome the defective of prior art, and it finishes being operated in the factory of cable branch, and the reliability of branch cable is improved greatly.
For achieving the above object, the technical solution of the utility model is: described crosslinked polyetylene insulated branch cable comprises backbone cable, branch cable and branch joint, this backbone cable is connected with branch cable and is made backbone cable and branch cable conducting by described branch joint.
The insulating material of branch cable of the present utility model adopts one-step silane cross-linked polyethylene, and its electrical property and physical property are more reliable.This branch cable has substituted the bus duct that involved great expense originally, greatly reduces project cost.Have good power supply reliability, be convenient to construction, shortened the engineering time, reduced labour intensity.Have waterproof and dampproof function, can be non-maintaining for a long time, exempt from maintenance.Low to the construction environment requirement, floor space is little, and bending radius is little, and specification, various in style selects for use mode flexible, also can be according to the engine request combination in any.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of branch joint in the branch cable shown in Figure 1;
Fig. 3 is the process flow chart of branch joint shown in Figure 2.
Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
See also Fig. 1: be a specific embodiment of the present utility model.This crosslinked polyetylene insulated branch cable comprises backbone cable 2, branch cable 1 and branch joint 3, this backbone cable 2 is connected with branch cable 1 and is made backbone cable 2 and branch cable 1 conducting by described branch joint 3.
Described backbone cable 2 and branch cable 1 comprise conductor 101,201 respectively, are wrapped in insulating barrier 102,202 and outermost sheath 103,203 outside this conductor 101,201.
It is one-step silane cross-linked polyethylene that described insulating barrier 102,202 adopts film-grade PE-, and extrusion equipment adopts the Three layer coextruding one step production of silane line of Finland Nokia-Mai Raphael company.This production line is a domestic unique production line, whole production line adopts system controlled by computer, and show, follow the tracks of the particulars in the production process at any time, and can carry out the technology adjustment to the abnormal conditions that occur in the production process at any time, the quality of product is guaranteed.
For preventing that small impurity or dust from entering insulating material, described one-step silane cross-linked polyethylene purifies through 1000 grades and adopts gravity blanking and make.Can guarantee raw-material degree of purity like this, the electrical property of the crosslinked polyetylene insulated layer that makes is well controlled.
Crosslinking agent adopts import silane, is injected automatically at the hopper neck by technological requirement by the automatic implanter of silane.Can make PE material and silane mixture even, make the crosslinked polyetylene insulated degree of cross linking that makes qualified, avoid crossing crosslinked or crosslinked deficiency.
Described sheath 103,203 is made by pvc material.
Described conductor 101,201 materials adopt the electrician's circular copper wire that meets national standard, and its long-term work temperature is 90 ℃, and the short circuit temperature is 250 ℃.
As shown in Figure 2, described branch joint 3 comprises bifurcation connector 301 and the branch joint cover 302 that annealing " C " the shape copper pipe of selecting high conduction performance for use is made, the copper core of described backbone cable 2 and branch cable 1 in splice housing 302 inner sealing peelings, is crimped on this bifurcation connector 301 two ends then.So just can reach waterproof, protection against the tide, effect such as dustproof, avoid joint contact position copper core to expose the increase that in air, produces oxidation and cause contact resistance, thereby guaranteed safety, the reliability of distribution system.
Be illustrated in figure 3 as the process flow chart of the branch joint 3 in the utility model.Wherein:
Operation 4 is a press, the joint that connects is compressed fasten under predetermined pressure;
Operation 5 is injection mo(u)lding, and the joint of suppressing is refilled the corresponding insulator global formation of cable;
Operation 6 is the take-up packaging system.
Wherein: the automatic injection machine is adopted in injection moulding.The system controlled by computer shot can make injection molding joint neat, unified, has also avoided artificial shot control uneven, and injection moulding is imperfect, easily infiltrates defectives such as impurity, the fail safe that has improved distribution system.
For making branch cable unwrapping wire safety, quick, last end bearing adopts and hangs header structure, and aluminium hydraulic pressed connecting pipe is selected the 45# steel for use, can guarantee the pulling force of whole cable; Hang head and select nylon material for use, can use for a long time, reach cable insulation and get purpose, therefore the electric leakage accident can not take place, cause casualties, can also play the effect of hermetically-sealed cable termination, stop entering of moisture and moisture, water tree breakdown accident takes place when avoiding the cable operation, has improved the reliability of distribution system.
Main line specification maximum of the present utility model can reach 1000mm
2, branch line specification and radical can be determined according to customer requirements.
Product of the present utility model also can be according to customer requirements insulate colour band phase-splitting or the phase-splitting of sheath color.
