Abstract
The utility model discloses a 35kV cable intermediate joint. The 35kV cable intermediate joint includes a joint body; a conductor connecting pipe is arranged in the joint body; a cable extends into the conductor connecting pipe from two ends of the joint body; conductor ends of the cable are symmetrically arranged inside the conductor connecting pipe; an insulating adhesive layer is sleeved on the periphery of the cable in the joint body; a semiconductor shielding layer is arranged between the conductor connecting pipe and the insulating adhesive layer; and a waterproof insulation adhesive tape layer is arranged between the insulating adhesive layer and the outer surface of the joint body. By means of the above manner, the 35kV cable intermediate joint of the utility model has the advantages of simple and compact structure, excellent performance and favorable waterproof property; and the 35kV cable intermediate joint can provide constant lasting radial pressure for a cable body, and long-term reliable operation can be ensured.
Description
Technical field
The utility model relates to field of cables, particularly relates to a kind of 35kV cable intermediate joint.
Background technology
Elastic rubber material has " elastic memory " characteristic, just as spring.Cold-shrink technology claims again the predilation technology, namely adopts mechanical means that the rubber parts of moulding is strutted in its elastic range in advance, then is inserted in the plastics core and is fixed.During installation, only need core is taken out, elastic rubbery body just shrink rapidly and lock ring in required installation position.
Insulating properties, heat-resisting quantity and the resistance to acids and bases of the cold-shrink type cable intermediate joint material of prior art itself are poor, cause the overall performance of transition joint poor, and the cold and hot swollen shrinkage in Electricity Federation is excessive, the waterproof sealing poor performance, and intensity is lower.
