Novel waterproof wiring terminal for on-column equipment cable terminals

Abstract

A novel waterproof wiring terminal for on-column equipment cable terminals is mainly composed of two parts: a wiring terminal and an insulating nut. The wiring terminal part is composed of a semi-circular copper port, a press-fitting metal part, and a rainproof U-shaped port. The insulating nut is used as a separate component. The semi-circular copper port of the wiring terminal is connected with an equipment pile head. The press-fitting metal part is connected with a cable wire core. The invention provides the novel waterproof wiring terminal for on-column equipment cable terminals which is manufactured by a simple technology, and is corrosion-resistant, durable, and easy to use. Rainwater can be prevented from entering the wire core from the connector at the joint of the wiring terminal and the wire core and flowing into a cable branch box connector under a rod. Therefore, the phenomenon of discharge insulation breakdown caused by rainwater is prevented, and safe operation of equipment is ensured. The novel waterproof wiring terminal is suitable for wide popularization in the technical field to which the novel waterproof wiring terminal belongs.

Description

Technical field: [0001] The invention relates to a new type of terminal connection terminal for waterproofing of the cable terminal conductor core of the equipment on the power distribution network column. Background technique: [0002] At present, with the development of urban power distribution networks, the development trend of overhead bare conductors being gradually replaced by cables. In order to facilitate the maintenance and operation, and there are obvious disconnect points to protect the safety of people and equipment. Outdoor cable terminals are generally equipped with post equipment and isolation equipment. Connect the cable terminal to this equipment or the joint of the isolation equipment, and set up a cable branch box under the pole to ensure segmental control of each cable line. Ensure the safe and stable operation of each line. [0003] According to the current site survey, the general cable terminal head terminal is cylindrical, the terminal cable core is insert...

AI Technical Summary

Problems solved by technology

The sealing tube of this terminal terminal is exposed to the air for a long time, and it will be corroded continuously over time, and eventually loses its sealing protection.

And from some inspections on site, sometimes it is found that some terminals and wire cores are directly crimped in order to save trouble, and the filling glue and sealant are not sealed, which will cause rainwater to flow from the terminal wire core on the pole It flows to the cable branch box under the pole, and due to the drop of water pressure, it flows to the terminal of the equipment and discharges, which eventually causes the insulation performance to be damaged and leads to accidents; in addition, the manufacturing process of some cables does not fully meet the requirements. There will be some burrs on the surface of the cable core. If rainwater enters, discharge will occur here and cause damage to the main insulation of the cable. In severe cases, short-circuit accidents may occur
