Description

Technical Field

[0001] This utility model relates to the field of cable waterproofing technology, and in particular to a waterproof sealing structure for wires and cables. Background Technology

[0002] Wires are conductors that transmit electrical energy, generally made of conductive materials such as copper or aluminum, and usually wrapped with an insulation layer. They are mainly used to transmit electrical energy or signals. Cables, on the other hand, consist of one or more insulated conductors, wrapped with a tough outer layer of metal or rubber. Cables are an assembly of one or more insulated conductors, and their structure is more complex than that of wires. Each conductor in a cable has its own insulation layer, and these insulated conductors are twisted or arranged in parallel. In multi-core cables, the cores are insulated from each other. This structure allows multiple signals or electrical energy to be transmitted simultaneously in a single cable. For example, in some control cables, control signals and power signals can be transmitted through different cores. Water is a good conductor of electricity. If wires and cables do not have a waterproof sealing structure, water will enter the cable and damage the insulation layer, which may also cause serious consequences such as electrical fires. Therefore, a waterproof sealing structure for wires and cables is needed.

[0003] The basic waterproof sealing structure for wires and cables consists of sealing materials, protective sleeves, and connection sealing structures. This waterproof sealing structure prevents liquid from entering the cable, avoiding safety accidents. Wires and cables have wide applications in many fields. In power plants, a large number of wires and cables are used to connect generators to transformers and switchgear equipment. In thermal power plants, the electrical energy generated by generators is transmitted to the plant's step-up transformers via high-voltage cables. These cables need to have high voltage levels and high current carrying capacity to ensure efficient and safe transmission of electrical energy. In ordinary residences, wires are used to connect indoor lighting fixtures, sockets, and various electrical appliances. Lighting fixtures are connected to lighting circuits in the distribution box via wires, and sockets are connected to socket circuits via wires. These wires generally use copper-core PVC insulated wires, which can meet the safety and functional needs of daily household electricity use. However, existing waterproofing measures for wires and cables generally suffer from poor waterproofing effects, inconvenient construction, high costs, and difficult maintenance. Especially under extreme weather conditions, the service life of cables is severely affected, posing a challenge to the safe and stable operation of the power grid. Utility Model Content
