Abstract
The utility model relates to a cold-shrink power cable terminal, which solves the problems that the prior cable terminals are high in the manufacturing cost and inconvenient for installation. The cold-shrink power cable terminal is characterized in that a cable (1) is connected with a cold-shrink fingerstall (2); the cold-shrink fingerstall (2) has multiple fingers (3), wherein each finger is connected with one end of a cold-shrink terminal (4), and a binding post (5) is connected with the other end of the cold-shrink terminal (4); a cold-shrink sealing pipe (6) wraps the connection position of the binding post and the cold-shrink terminal, wherein a waterproof adhesive tape layer (8) is covered between the cold-shrink sealing pipe (6) and the binding post; and cold-shrink rain skirts (7) are moulded individually and then sleeved on the cold-shrink terminal (4), wherein the length of the cold-shrink terminal (4) is 400-600mm.
Description
Technical field:
The utility model and power cable and switch cubicle or transformer to be connected terminal structure relevant.
Background technology:
10-35kV power cable terminal structure, the function of electric field strength, insulation and the water-tight of needs control power cable shield end.After installing, this terminal is connected with switch cubicle or transformer.The shrinkage power cable terminal from last century the eighties Minnesota Mining and Manufacturing Company succeed in developing, installation and the making of power cable terminal have been widely used at present, domestic also have a lot of producers, its structure is similar: take three core 10kV cables as example, behind the strip off cable cover(ing), cable armouring and bonding are handled well, be inserted in the shrinkage fingerstall; Every being mounted to mutually lacked a cold shrink tube, and then cold shrink tube and fingerstall finger overlap joint peel off unnecessary copper shield and semi-conductive screen, and cold-shrinkable terminal head (with the cold shrink tube overlap joint) is installed.After terminals are installed, peel off suitable main insulation, the crimping binding post, the shrinkage sealed tube is installed again, overlap joint terminals and binding post, shown in Figure 1, its weak point is that each producer's cold-shrinkable terminal head is shorter at present, its length can not satisfy the requirement of cable phase-splitting, therefore at least one cold shrink tube 9 must be installed, to lengthen the phase-splitting distance.
The utility model content:
The purpose of this utility model provides a kind of simple in structure, and is easy to manufacture, easy for installation, shrinkage power cable terminal with low cost.
The utility model is achieved in that
The utility model shrinkage power cable terminal, cable 1 is connected with shrinkage fingerstall 2, shrinkage fingerstall 2 has several fingers 3, each finger is connected with an end of a cold-shrinkable terminal head 4, and the other end of cold-shrinkable terminal head 4 is connected with binding post 5, and shrinkage sealed tube 6 contains the junction, be coated with marine glue belt 8 between shrinkage sealed tube 6 and the binding post, the 7 independent injection mouldings of shrinkage rain skirt are enclosed within outside the cold-shrinkable terminal 4, and the length of cold-shrinkable terminal head 4 is 400-600mm.
The length of cold-shrinkable terminal head 4 is 500mm.
The utility model has significantly increased the length of cold-shrinkable terminal head, and cold shrink tube can be installed, and reduces production costs about 25%.Economize cold shrink tube is installed, easier for installation.Cold-shrinkable terminal separates manufacturing, low cost of manufacture, good product quality with full skirt.
Description of drawings:
Fig. 1 is existing shrinkage power cable terminal structure chart.
Fig. 2 is the utility model structure chart.
Embodiment:
At present about the about 210mm of the indoor cold-shrinkable terminal head of each producer, about the about 290mm of outdoor termination, the utility model is made shrinkage rain skirt 7 separately, the length of indoor, outdoor cold-shrinkable terminal head all is increased to 500mm, just a cold shrink tube 9 can be installed less mutually whenever in its structure, cold-shrinkable terminal head 4 and shrinkage fingerstall 2 overlap joints, the other end of cold-shrinkable terminal head 4 is connected with binding post 5, there is shrinkage sealed tube 6 to contain the junction, marine glue belt 8 is arranged between shrinkage sealed tube 6 and the binding post.Other structure is same as the prior art.Operation principle adopts the electric field strength of stress cone control power cable shield end, and utilizes good elasticity and the insulation property of silicon rubber of cold-shrinkable terminal head 4 and shrinkage sealed tube 6 to play good sealing function and reach good insulation effect.The shrinkage rain skirt 7 of making separately is enclosed within outside the cold-shrinkable terminal 4, expands with cold-shrinkable terminal, shrinks together during installation, relies on elasticity to hold tightly on cold-shrinkable terminal head 4.Low cost of manufacture, good product quality.
Claims (2)
1. shrinkage power cable terminal, it is characterized in that cable (1) is connected with shrinkage fingerstall (2), shrinkage fingerstall (2) has several fingers (3), each finger is connected with an end of a cold-shrinkable terminal head (4), the other end of cold-shrinkable terminal head (4) is connected with binding post (5), shrinkage sealed tube (6) coats the junction, be coated with marine glue belt (8) between shrinkage sealed tube (6) and the binding post, shrinkage rain skirt (7) is enclosed within outside the cold-shrinkable terminal head (4) after the moulding separately, and the length of cold-shrinkable terminal head (4) is 400-600mm.
