The utility model discloses a shrinkage explosion -proof type cable intermediate head upper portion both ends are provided with lets out the ability hole, fills the sealed back of gluing of high tension cable through this hole, has strengthened the sealed function that connects, has avoided the emergence of exploding.
Description
Technical field
The utility model relates to a kind of intermediate head, is specifically related to a kind of shrinkage explosion-proof type cable intermediate joint, belongs to cable splice technical field.
Background technology
Existing cold contract cable middle joint cannot solve waterproof problem, a lot of cable intermediate joint often operate in tunnel, the place of inferior humidity, it is easy to have moisture to enter, thus cause joint short circuit, massive losses is brought to user, traditional cold contract cable middle joint is due to long-time running or accident, spontaneous combustion or blast may be there is, and other cable can be injured in cable trench or cable testing bridge, lose inestimable, traditional cold contract cable middle joint is due to long-time running or accident, it is possible to spontaneous combustion or blast occur.
Practical novel content
For solving the problem, the utility model proposes a kind of shrinkage explosion-proof type cable intermediate joint, its good insulating, it is possible to avoid having an accident.
Shrinkage explosion-proof type cable intermediate joint of the present utility model, comprises shrinkage joint, and is arranged at the armored cassette of shrinkage joint periphery; Described shrinkage joint comprises triple core cable, and is set in turn in the steel armour outside triple core cable, big constant force spring and inner sheath of cable; And be arranged at little constant force spring and the copper shield of three core peripheries of triple core cable, and the semi-conductive layer installed with three cores of triple core cable successively, core insulation layer and conductor connecting tube; And be arranged at the shrinkage intermediate head of semi-conductive layer, core insulation layer and conductor connecting tube periphery, and it is arranged at the copper net of shrinkage intermediate head periphery; And the wide PVC being arranged at triple core cable periphery is with; And it is arranged at the copper braid of wide PVC band periphery; And it is arranged at copper braid internal layer and outer field adhesive waterproof tape; And it is arranged at the armoring tape of adhesive waterproof tape periphery; Described armored cassette both upper ends thereof be provided with lets out can hole, described in let out and can be perfused with high-tension cable seal gum in hole, its peripheral fabricated section of described triple core cable is symmetrical arranged in armored cassette two ends.
As preferred embodiment, described armored cassette is the composite material sealing box such as sealed nylon box or fiberglass sealed box.
Compared with prior art, shrinkage explosion-proof type cable intermediate joint of the present utility model, can carry out well sealing waterproof in joint the utility model by pouring into high-tension cable seal gum; And its fire-protection rating reaches V0 level, it is possible to avoid on fire; Shrinkage explosion-proof type cable intermediate joint both upper ends thereof of the present utility model is provided with and lets out energy hole in addition, after pouring into high-tension cable seal gum by this hole, enhances the sealing function of joint, avoids the generation of blast.
Accompanying drawing explanation
Fig. 1 is embodiment 1 one-piece construction schematic diagram of the present utility model.
