Description
Technical field
The invention belongs to technical field of cable, and in particular to a kind of underground cable of reserved branch mouth and its manufacturer
Method.
Background technique
Buried route is compared with overhead transmission line, and buried route does not need the materials such as line bar, porcelain insulator, bracing wire, due to ground
In the laying path sunken cord, need to install branch line according to different spacing, the connector of installation site needs to carry out waterproof well
Processing, due to branch location generally apart from water source it is closer, it is easy to by moisture corrode and cause cable shorted to earth, thus shadow
The normal use of cable is rung, and there are some potential safety problemss, meanwhile, when traditional mode of production branch cable, to technical requirements
Relatively high, stability is difficult to control, while also inflexible, and installation is inconvenient, if design has change, it is not easy to quickly and effectively
Make a response.
A kind of manufacturing method of the agricultural underground cable of reserved branch mouth, step difference are disclosed this CN102903459A
Connect wire clamp for production J-type, the insulating layer outside removing main cable and external sheath layer, J-type connect wire clamp and conductor connection,
The connection of U-shaped card and injection molding sealing composition, cable produced by the invention can according to the design length of cable, cable _
Upper pre-manufactured waterproof bifurcations, it is not necessary to remake bifurcations, only be needed at bifurcations by the anti-water cutting of cable
External sealing is carried out after the reserved socket of head reeve cable, the sealing effect at cable connector increases substantially, and cable applies
If when only need unwrapping wire primary, compared with existing agricultural underground cable, the unwrapping wire time is greatly shortened, and reduce unwrapping wire hardly possible
Degree reduces the probability of existing damage cable during unwrapping wire, and the stable operation after preferably ensuring cable laying, cable is complete
After the laying of certain length, need extended, there is reserved socket in the end point of above-mentioned cable.
But above scheme has the following deficiencies:
Corresponding cable is mainly docked by the long end of J-type connection wire clamp is corresponding with main cable progress, but after giving in this way
Continuous injection molding etc. brings corresponding inconvenience, while corresponding aluminium sheet front end uses the processes such as corresponding screw hole and metal bar more
It is cumbersome.
