High-voltage solid-closed type cable intermediate joint

Abstract

The invention discloses a high-voltage solid-closed type cable intermediate joint. The high-voltage solid-closed type cable intermediate joint comprises an intermediate joint main body, the outside of the intermediate joint is sleeved by a nanometer keel net, the nanometer keel net is fixed through a band, the middle part and two ends of the nanometer keel net are respectively provided with a three-port glue-pouring valve and two exhaust pipes, the outside of the nanometer keel net is encapsulated by an antistatic film, the outside of the antistatic film is encapsulated by a PVC band and a waterproof adhesive tape in sequence, port encapsulating positions at two sides of the antistatic film and the PVC band and port encapsulating positions at two sides of the PVC band and the waterproof adhesive tape are all sealed by employing sealant, the glue-pouring valve and the exhaust pipes are encapsulated by the antistatic film, the PVC band and the waterproof adhesive tape, only an upper port of the glue-pouring valve communicates with the nanometer keel net, glue is poured into the glue-pouring valve until tail pipes of the exhaust pipes are filled with glue, the outside of the waterproof adhesive tape is sleeved by an armored tape, and the outside of the armored tape is provided with a protective shell. According to the high-voltage solid-closed type cable intermediate joint, the structure is reasonable and reliable, the service lifetime is long, and the fireproof and moisture-proof performances are good.

Description

technical field [0001] The invention relates to an intermediate joint, in particular to a high-voltage solid-sealed cable intermediate joint. Background technique [0002] With the popularization of power cable engineering, the rate of cable accidents has also increased. A large number of facts have proved that most cable accidents are related to cable accessories, especially cable intermediate joints. In the existing cable intermediate joints, in order to prevent moisture from entering the intermediate joint, the waterproof tape is generally used to wrap the end of the joint body. There are still gaps between them, the sealing is poor, and moisture may enter through it. In addition, the general cable intermediate joints are not treated with fire protection, and there are still serious safety hazards in the use of power cables. Contents of the invention [0003] The object of the present invention is to provide a high-voltage solid-sealed cable intermediate joint with rea...
