Abstract
The utility model relates to a thermal shrinkage terminal for a three-core crosslinked cable, which is provided with three conductor cores. The conductor cores are sleeved with insulating tubes; one end of each of the conductor cores is provided with a terminal; sealed tubes are arranged below the terminals; single-hole rainproof skirts are arranged in the middle part of the conductor cores and on the insulating tubes; the other ends of the three conductor cores respectively penetrate through the holes of a three-hole rainproof skirt and are wrapped together by a PVC sheath; a glove is arranged outside the PVC sheath; an earth wire is arranged between the glove and the PVC sheath; and a copper shielding layer is arranged in the PVC sheath. The utility model simplifies the structure of the original thermal shrinkage terminal, and improves the safety in the real application in power circuits.
Description
One, technical field
The utility model belongs to electrical equipment technical field, particularly a kind of three core crosslinked cable thermal shrinkage type terminals.
Two, background technology
Prior art: in recent years, along with rapid economic development, urbanization process is accelerated, the startup of the carrying out in a deep going way of the upgrading of rural power grids, urban network restructuring, and the use of power cable in electric power system is more and more widely.In the eighties in 20th century, the power cable manufacturing technology obtains upgrading, and crosslinked polyethylene (XLPE) insulation has progressively replaced original paper oil insulation and obtained develop rapidly, at present the domestic XLPE insulated power cable that can produce the 500kV electric pressure.And as the essential electric cable accessories of cable system operation also along with more new development and develop rapidly continues to bring out various novel accessory product in recent years of cable technology.The thermal shrinkage type terminal is still occupied leading position in 10～35kV crosslinked cable annex.But present thermal shrinkage type terminal causes safety in utilization low because there is incomplete place in structure.
Three, summary of the invention
Technical problem: the utility model provides a kind of three core crosslinked cable thermal shrinkage type terminals at above-mentioned technological deficiency, and these terminals are simple in structure, the fail safe when having improved practical application.
Technical scheme: technical solution of the present utility model is: a kind of three core crosslinked cable thermal shrinkage type terminals, these terminals are provided with the compenzine core, be with insulated tube on the core, one end of per share core is provided with terminal, the terminal below is provided with sealed tube, and the middle part of core, insulated tube are provided with the single hole Rain-proof skirt, and the other end of compenzine core passes the hole of three hole Rain-proof skirts respectively and is bundled together by the pvc sheath, the pvc sheath is provided with gloves outward, is provided with earth connection between gloves and pvc sheath.Be provided with copper shield in the described pvc sheath.
Beneficial effect: when the utility model has been simplified original thermal shrinkage type terminals structure, improved its fail safe during practical application on power circuit.
Four, description of drawings
Fig. 1 is the structural representation of three core crosslinked cable thermal shrinkage type terminals.Terminal among the figure (1), sealed tube (2), insulated tube (3), single hole Rain-proof skirt (4), three hole Rain-proof skirts (5), gloves (6), pvc sheath (7), earth connection (8).
Five, embodiment
Embodiment 1: a kind of three core crosslinked cable thermal shrinkage type terminals, these terminals are provided with the compenzine core, be with insulated tube 3 on the core, one end of per share core is provided with terminal 1, the terminal below is provided with sealed tube 2, and the middle part of core, insulated tube are provided with single hole Rain-proof skirt 4, and the other end of compenzine core passes the hole of three hole Rain-proof skirts 5 respectively and is bundled together by pvc sheath 7, the pvc sheath is provided with gloves 6 outward, is provided with earth connection 8 between gloves and pvc sheath.Be provided with copper shield in the described pvc sheath.
