Abstract
The utility model relates to a waterproof a cold-shrinking intermediate head of cables. The utility model solves technical problems and the waterproof the cold-shrinking intermediate head of the cables in the utility model has characteristics of good sealing performance, good mechanical strength and long service lifetime. The technical scheme is that the waterproof cold-shrinking intermediate head of the cables includes an intermediate head sleeved between connecting terminals of the two cables. It is characterized in that the intermediate head is also sleeved with a cylindrical metal shell. The cylindrical metal shell is also wrapped with a thermal shrinkage sheath pipe. Two necking-in metal shells are inserted in two ends of the cylindrical metal shell respectively. And the necking-in metal shells in the two ends of the intermediate head are wrapped completely by two thermal shrinkage sheath taper pipes. The cylindrical metal shell is made from iron sheets. The necking-in metal shell is made from the iron sheets.
Description
Technical field
The utility model relates to a kind of cable fitting, especially cable waterproof shrinkage transition joint.
Background technology
The shrinkage transition joint is widely used in coastal area wind power generation 35kV circuit; Owing to be directly buried installation mostly, and is mostly area, saline and alkaline seabeach, to the waterproof sealing and the anticorrosion of transition joint, prevent that mechanical damage has proposed high requirement.The structure of existing shrinkage transition joint is as shown in Figure 3; Though simple in structure, the waterproof sealing performance still can not satisfy instructions for use.
Summary of the invention
The utility model technical problem to be solved is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of cable waterproof shrinkage transition joint is provided, and this transition joint should have the characteristics of good seal performance, mechanical strength height and long service life.
The technical scheme that the utility model provides is:
Cable waterproof shrinkage transition joint comprises the transition joint that is socketed in two cable joint ends, it is characterized in that the outside of said transition joint also wears a tubular metal shell, and the outside of tubular metal shell is intactly coated by the pyrocondensation protecting pipe again.
The two ends of the said tubular metal shell closing in metal shell of pegging graft respectively; And all intactly coat the closing in metal shell at transition joint two ends by two pyrocondensation sheath Taper Pipes respectively.
Said tubular metal shell adopts iron sheet to make.
Said closing in metal shell adopts iron sheet to make.
The beneficial effect of the utility model is: the outside of transition joint wears iron sheet tube; After coating the pyrocondensation protecting pipe again; Mechanical performance and decay resistance have all had significantly raising, and the waterproof sealing performance also has significant enhancing, has guaranteed normally carrying out of power cable work.
Description of drawings
Fig. 1 is the main TV structure sketch map of the utility model.
Fig. 2 is the deployed condition sketch map of the closing in iron sheet tube in the utility model.
Fig. 3 is the main TV structure sketch map of existing transition joint.
Embodiment
As shown in Figure 3, cable waterproof shrinkage transition joint comprises the transition joint 1 that is socketed in two cable 2 tip sides; The structure of this transition joint normally adopts the core of two cable joints of tube connector crimping, and then coats the shrinkage gum sleeve.More than structure with conventional transition joint identical, so the sectional structure view of transition joint omits.
The improvement of the utility model is also to wear a tubular metal shell 3 (recommending to adopt iron sheet to make) in the outside of said transition joint 1, and the outside of tubular metal shell is intactly coated by pyrocondensation protecting pipe 7 again.The pyrocondensation protecting pipe is generally crosslinked polyethylene pipe, and pyrocondensation coats and is made as common process, and concrete coating is made and must be carried out in the erecting bed.
Further, the two ends of the said tubular metal shell closing in metal shell 5 (recommend adopt iron sheet make) of pegging graft respectively; And all intactly coat the closing in metal shell at transition joint two ends by two pyrocondensation sheath Taper Pipes 6 respectively.Can be known by Fig. 1: the two ends port of pyrocondensation sheath Taper Pipe tightly blocks is respectively pressing the surface of cable 2 and the surface of pyrocondensation protecting pipe 7, all slits is all sealed, so the waterproof sealing performance is significantly improved.
The deployed condition of said closing in metal shell is as shown in Figure 2; Can adopt existing sheet metal process to make.
