Description
Technical field
The utility model relates to a kind of cable, refers in particular to the armored prefabricated branch cable of a kind of improvement.
Background technology
Paying branch cable in advance is meant by prefabrication and becomes complete continuous cable assembly; In main cable regulation position and requirement thereof; With the conductor of main cable and branch cable, connect through copper or copper alloy tube compression, and carry out complete insulation processing (JB/T10636-2006).The branch cable structure mainly is divided into two kinds, and a kind of is single core prefabricated branch cable, and another kind is the multicore prefabricated branch cable, and its extensively suitable skyscraper, large-scale standardization factory building, comprehensive culture and education body are defended facility and means of transportation such as highway, bridge tunnel.Later stage nineteen seventies begins to develop branch cable abroad, begins to drop into a large amount of uses the eighties.The prefabricated branch cable technology of Japan is the most advanced and ripe, and successively issue JCS 376A-2002 " band branch cable " and JCS427-2000 " 600v environment-friendly type band branch cable " standard.China had issued the first building trade prefabricated branch cable standard of JG/T 147-2002 " the prefabricated branch of rated voltage 0.6/1kV copper core plastic insulation power cable " in 2003, issued JB/T 10636-2006 " rated voltage 0.6/1kV (Um=1.2kV) copper core plastic insulation prefabricated branch cable " standard in 2006 again.The insulating material of branch cable is a polyvinyl chloride insulation and crosslinked polyetylene insulated, and sheath material then is pvc sheath or polyolefin jacket, and product type more has fire-retardant, fire-resistant, low smoke and zero halogen.Yet above standard is not all stipulated armouring type prefabricated branch cable.In the engineering actual demand, under part buried or the serious zone of the plague of rats or tunnel, cable trough and other the many gravels environment, how guaranteeing to pay in advance the normal operation of branch cable has been an inevitable problem.As prevent cable lay or running in the mechanical damage and the chemoproection that possibly be subjected to, and its effect of metal armouring layer of bearing certain external force can not be ignored.
Chinese patent had once been announced " a kind of armored prefabricated multicore branch cable " (China; Notification number CN101783201A; Date of publication 2010.07.21); Comprise overall outer layer insulation sheath and interior leader cable, leader cable armour, branch cable and the branch cable armour of overall outer layer insulation sheath; Leader cable and branch cable are crimped on through connector and form branch's connected body together, and branch's connected body is provided with branch's connected body armour outward, and leader cable armour and branch cable armour are welded into an integral body through branch's connected body armour.But it is in application process; Owing to there is certain defective, possibly occur sending a telegraph because of armour weld convexity is not docile cable when bending, insulate impaired punctures or weld occur in the not firm BENDING PROCESS rupturing or appearance damages bad phenomenon generations such as inner sheath because of welding temperature is too high.
The utility model content
The purpose of the utility model is to provide a kind of improvement armouring type prefabricated branch cable, and it goes for the environment that the buried or serious zone of the plague of rats or tunnel, cable trough and other many gravels are subject to foreign impacts.
For achieving the above object; The solution that the utility model is taked is: a kind of improvement armouring type prefabricated branch cable, and it comprises main cable conductor and branch cable conductor, the main cable conductor extrudes the main cable insulation; Form the main cable insulating core; Stranded and the wrapped main cable twining package tape of main cable insulating core, the main cable twining package tape is followed successively by main cable inner sheath, main cable steel-tape armouring, main cable oversheath outward, forms main cable; The branch cable conductor extrudes the branch cable insulation outward, the outer wrapped branch cable twining package tape of branch cable insulation, and the branch cable twining package tape is followed successively by branch cable inner sheath, branch cable steel-tape armouring and branch cable oversheath outward, forms branch cable; Main cable and branch cable are peeled off respectively to main cable conductor and branch cable conductor; Main cable conductor and branch cable conductor junction compress insulating case in the back mold pressing injection moulding connector with C shape pipe; Wrapped one deck high strength outside the insulating case, the adiabatic turnkey buffer zone of high resiliency in connector compress wrapped successively composite steel-plastic belt behind high strength, the adiabatic turnkey buffer zone of high resiliency, fastening woven steel fabric, wrapped nonwoven fabric belts, the mold pressing injection moulding connector injection moulding oversheath tightened.
This kind improvement armouring type prefabricated branch cable is applicable to the serious zone of the buried or plague of rats or tunnel, cable trough and other many gravels environment fully.
