Abstract
Disclosed is a rubber jacket cable hot vulcanizing method with which the vulcanized cable is of no upwrapped fringes and no slip cracks. The method includes the following steps: first, wrap the core wire with core wire rubber, then enwind the core wire with beeswax, wind the three-phase core wire with beeswax, wind a vulcanizing adhesive tape onto the core wire, wind a high temperature resistant plastic film at the outer layer of the adhesive tape through double-layer half compression, at last heat the cable in a die until the temperature reaches 180 degrees, then tighten the die when the temperature drops to 120 degrees, finally get out the cable when the temperature drops to 80 degrees. The method is used in mending and jointing coalmine low voltage rubber jacket cables, and the joint made with the method is as smooth as a new cable, without upwrapped fringes and slip cracks, thus improving cable mending quality, reducing downhole power supply safety troubles and reducing the investment of talcum powder.
Description
Technical field
The present invention relates to a kind of cable repairing method, relate in particular to a kind of rubber sleeve cable hot patching method.
Background technology
Present low pressure Plastic-sheathed Cable is repaired, is connect method greatly: with heart yearn glue wrapping heart yearn, twine in accordance with regulations with linotape more earlier, and then with yellow cured band the triple line tangle up, be wrapped with at last and vulcanize adhesive tape, be placed in the mould after handling well and heat.If temperature control is bad, easily the adhesive tape of vulcanizing that twines is scalded, even spread many again talcum powder, also can stick together cable and mould, waste time and energy when playing mould, often cause the cable repairing quality low, alice, aliquation.Such cable is in use the down-hole, and alice, aliquation place intake easily, make moist and tear and cause ground connection, electric leakage, short circuit accident, have both influenced safety in production, have buried hidden danger for safe power supply again.
Summary of the invention
The purpose of this invention is to provide a kind of rubber sleeve cable hot patching method of repairing the no alice in back, no aliquation.
For achieving the above object, the technical solution used in the present invention is:
A kind of rubber sleeve cable hot patching method, earlier with heart yearn glue wrapping heart yearn, twine heart yearn with linotape again, use yellow cured band three-phase heart yearn tangle up then, be wrapped with subsequently and vulcanize adhesive tape, its characteristics are: be wrapped with the thermostable transparent plastic film again at the skin of vulcanizing adhesive tape, and then put mould into and heat, heating-up temperature reaches 180 and stops heating when spending, and is cooled to 120 tight moulds when spending, and is cooled to 80 and takes out cable when spending and get final product.
Connecing greatly that extrusion comes in this way is not only smooth but also do not have phenomenons such as alice, no aliquation, as the cable smooth and beautiful appearance of just having dispatched from the factory.Not only improve the cable repairing quality, reduced downhole safety power supply hidden danger, the input of also having saved materials such as talcum powder.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further described:
A kind of rubber sleeve cable hot patching method, earlier with heart yearn glue wrapping heart yearn, twine heart yearn with linotape again, use yellow cured band three-phase heart yearn tangle up then, be wrapped with subsequently and vulcanize adhesive tape, adopt double-deck half platen press to be wrapped with the thermostable transparent plastic film again at the skin of vulcanizing adhesive tape, and then put mould into and heat, heating-up temperature reaches 180 and stops heating when spending, and is cooled to 120 tight moulds when spending, and is cooled to 80 and takes out cable when spending and get final product.
The present invention through budget every year can economical with materials take drop into 18000 surplus yuan.Minimizing because of alice, aliquation place intake easily, make moist cause ground connection, electric leakage, short circuit accident influence produce and the accident maintenance fee of material drop into 85000 surplus yuan.
The present invention can effectively improve the cable repairing quality, stop to intake easily, make moist and cause the phenomenon that ground connection, electric leakage, short circuit accident influence production because of alice, aliquation place, improve the fail safe and the reliability of down-hole low pressure Plastic-sheathed Cable power supply, make low pressure Plastic-sheathed Cable after the reparation as the cable smooth and beautiful appearance of just having dispatched from the factory.
Claims (1)
1. rubber sleeve cable hot patching method, earlier with heart yearn glue wrapping heart yearn, twine heart yearn with linotape again, use yellow cured band three-phase heart yearn tangle up then, be wrapped with subsequently and vulcanize adhesive tape, it is characterized in that: be wrapped with the thermostable transparent plastic film again at the skin of vulcanizing adhesive tape, and then put mould into and heat, heating-up temperature reaches 180 and stops heating when spending, and is cooled to 120 tight moulds when spending, and is cooled to 80 and takes out cable when spending and get final product.
