Description

Technical Field

[0001] The utility model relates to the technical field of branch cables, in particular to a pre-branched double-layer high-performance insulated cable. Background Art

[0002] With the strong growth of China's national economy, the speed of various infrastructure construction and real estate development has accelerated. It is inevitable to use power cables as the main power supply and distribution lines in various buildings and facilities. Therefore, construction units, design units, and construction contractors are all looking for more advanced, more economical, superior in performance, occupying less effective space, and having a shorter construction period power supply and distribution construction technologies and methods. The pre-branched cable is a cable in which the factory prefabricates branch lines according to the user's design drawings when producing the main cable. It is a new technology product in recent years and has the advantages of reliable power supply, convenient installation, good waterproof performance, small floor area, low failure rate, low price, and maintenance-free. It is widely used in vertical power supply in the electrical shafts of high-rise buildings, residential buildings, commercial buildings, hotels, and hospitals, and is also applicable to power supply systems such as tunnels, airports, bridges, and highways. It is precisely under such historical environmental conditions that pre-branched cables have stepped onto the stage of China's building electricity.

[0003] Since pre-branched cables are mainly used in places with a large number of people or sites for storing valuable items, there are relatively high requirements for the fire prevention performance and safety of pre-branched cables. The connection part between the main cable and the branch cable in the pre-branched cable is a part that is easily damaged in the cable. In ordinary pre-branched cables, a protective layer is generally coated outside the connection part. When a fire occurs, the protective layer is easily burned out and falls off from the connection part, thus losing the function of protecting the connection part of the pre-branched cable, and unable to ensure the smooth flow of power and information control in case of fire, which causes a major obstacle to the escape and survival of people in the fire. For this reason, a pre-branched cable (specifically refer to the patent number: 201620475314.1) is provided, which relates to the technical field of power cables and is designed to solve the technical problem that the protective layer coated outside the connection part between the main cable and the branch cable in the prior art is easily detached in a fire and cannot play a role in protecting the connection part of the pre-branched cable. The pre-branched cable includes a main cable and a branch cable connected to the inside of a branch joint through a coupling member; the branch joint is a ceramized polyolefin branch joint. The ceramized polyolefin branch joint of the utility model can generate a hard ceramic-like hard shell in a fire, and the hard shell has heat insulation and fire insulation characteristics, which can protect the connection part between the main cable and the branch cable from the influence of fire.

[0004] However, for some existing pre-branched cables, the connection work is relatively inconvenient, resulting in an extended connection time. At the same time, the connection is also relatively insecure. And when the branch is not needed, the device needs to be replaced, which is relatively inconvenient to use. Some pre-branched cables cannot perform the position adjustment work of the branch cable and can only be connected at a single position, with poor practicability. Summary of the Invention
