Abstract
The invention discloses a method for manufacturing an agricultural buried cable with a reserved branch opening. The method comprises the following steps of: manufacturing J-shaped connecting wire clamps; peeling off insulating layers and outer jacket layers outside main cables; connecting the J-shaped connecting wire clamps and conductors; connecting U-shaped clamps; and injection molding and sealing. According to the design length of the cable which is produced by using the method, a waterproof branch opening is pre-manufactured on the cable, a branch opening is not required to be re-manufactured, a waterproof plug of the cable is plugged into a reserved socket of the cable at the branch opening, and external sealing is performed, so a sealing effect of a cable joint is greatly improved, and the cable is required to be unwound for one time during cable laying. Compared with the conventional agricultural buried cable, the agricultural buried cable has the advantages that unwinding time is greatly shortened, unwinding difficulty is reduced, the probability of cable damage in the unwinding process is reduced, the cable can stably operate after being laid, and after the cable with certain length is laid, because a socket is reserved at the end head of the cable, the cable can be extended.
Description
Technical field
The present invention relates to electricapparatus and equipment manufactures field, particularly relate to a kind of manufacture method of agricultural underground cable of reserved branch mouth.
Background technology
At present, the low-voltage supply line that in farmland, power supply adopts, there are overhead transmission line and two kinds, buried circuit, buried circuit is compared with overhead transmission line, buried circuit does not need line bar, porcelain insulator, the materials such as bracing wire, a large amount of electrical materials can be saved, simultaneously because underground line does not need the pulling force considering cable deadweight, in farmland, the cross section of cable and the length of circuit and trend can be selected more flexibly, simultaneously because underground line is concealed work, the line bar not having crisscross gauze and stand in great numbers, very large convenience is brought to field farming, saved a large amount of arable lands simultaneously, because buried circuit is in underground, be not subject to violent storm, the invasion and attack of the natural calamities such as heavy snow freezes, there is not the bar that overhead transmission line is common, the accidents such as broken string, also can effectively avoid busy farming season because of line fault or damage or other a variety of causes and the farmland fire caused, the further safety having ensured people's life's property, lay in path due to underground line, need, according to different spacing, branch line is installed, the joint of installation site needs well to carry out water-proofing treatment, because branch location general distance water source is nearer, be easy to be subject to moisture corrode and cause cable shorted to earth, thus affect the normal use of cable, and there is certain potential safety hazard, simultaneously, when traditional mode of production branch cable, higher to technical requirement, stability is difficult to control, simultaneously also underaction, install inconvenient, if be designed with change, be not easy to make a response fast and effectively.
Summary of the invention
