Abstract

The invention discloses a transparent security box of a cable intermediate head, which is made from panlite or modified panlite. Flanges of two protruding semi-cylinders or semi-prismoids in the middle of the security box are connected into a whole by fastening bolts; a sealing fin is arranged between the flanges; circular holes are arranged at joints of two ends of the transparent security box and a cable; the two ends of the transparent security box are provided with seal grooves; the seal grooves are provided with seal cartridges; and the sealing fin and the seal cartridges are made from modified rubbers or synthetic rubbers or polyurethane resins or modified polyurethane resins. The transparent security box has performances of acid-base resistance, explosion prevention, lightning protection, fire protection and watertightness, is completely insulated, can bear impacts without deformation, is utilized to quickly understand states and environments in the security box by eyes, observes faults in advance and then processes the faults in real time. The security box can be utilized to sufficiently solve the problem of spontaneous ignition or blast injuries generated by long-time running of the cable intermediate head and other problems of the cable, and can effectively prevent accidents.

Description

technical field [0001] The invention belongs to the technical field of electric power or communication cable auxiliary devices, and relates to an explosion-proof, lightning-proof, fireproof and waterproof transparent safety box for cable intermediate joints. Background technique [0002] At present, overhead cables or underground cables are generally used for transmission in power, communication and cable TV transmission. There are many joints at the connection between the cables, and the joints are prone to aging during long-term use, causing sparks, short circuits, even explosions, and even fires, causing heavy losses. Fires caused by cable joints account for the vast majority of accidents. Therefore, untreated cable joints have great potential safety hazards. People are developing explosion-proof, lightning-proof, fire-proof and waterproof cable intermediate joint safety boxes through various efforts. The following is a brief description of what we retrieved from the li...
