As an important component of the power transmission system, the safe and stable operation of cable conduits is of great significance for ensuring the reliability and continuity of power supply. In future development, cable conduits will continue to play a crucial role in power transmission, contributing to the prosperity and stability of society. The testing of cable conduits covers multiple aspects such as material, size, bending performance, sealing performance, insulation performance, compression resistance, and impact resistance. The purpose of these tests is to ensure that the quality of cable conduits meets relevant standards and requirements, thereby ensuring the stability and safety of power transmission.

The size and specifications of cable conduits must comply with design requirements and relevant standards. The test includes the diameter, length, wall thickness, bending radius, etc. of the catheter. Use a bending tester or bending block for testing to simulate the bending of cable conduits in actual use. Bend the conduit within the specified bending radius and observe whether there are any cracks, indentations, or other deformations on its surface, in order to determine whether its flatness meets the standard requirements. For cable conduit joints, sealing tests are required to ensure they do not leak. The testing methods include hydrostatic testing and pneumatic testing, which observe the sealing performance of the joint by applying a certain amount of pressure.

Cable conduit, also known as cable protection conduit, is a tubular structure used to protect power facilities such as cables and wires from external environmental damage, mechanical damage, and fire threats. It is usually made of materials such as metal, plastic, ceramics, etc., and has excellent insulation, corrosion resistance, and flame retardant properties. According to different application scenarios and requirements, cable conduits can be divided into various types, such as power cable conduits, communication cable conduits, oil and gas pipeline cable conduits, etc.

With the rapid development of technology and the acceleration of urbanization, as one of the indispensable energy sources in modern society, the safety and stability of power transmission and distribution systems are particularly important. In this context, cable conduits, as an important component of the power transmission system, bear the important mission of ensuring the smooth flow of electricity.
