The bending radius of the cable and its influence on the cable 1. What is the bending radius of the cable? Cables must be actively or passively subjected to bending during the manufacturing, transportation, and installation and construction processes. When the cable is bent, the degree of bending is directly related to the bending radius of the cable. 1. The bending radius of the cable: Normally, we regard the bent cable as an arc, and the radius of the circle where the arc is located is the bending radius of the cable in the bend... more

Precautions for installation of flame-retardant and fire-resistant cables The characteristics of flame-retardant and fire-resistant cables: have the function of self-extinguishing, and can maintain the normal operation of the electrical circuit for a period of time under burning conditions. Therefore, the installation of flame-retardant and fire-resistant cables can effectively control major disasters caused by cable fire and prolonged combustion, thereby improving the fire protection level of electric lines. So, what matters should... more

Talking about Special Cable and Its Diversified Development Direction1. What is a special cable? What is the difference with ordinary cables?Special cables are cables that have special uses and can be used on specific occasions. Special cables are a series of products with unique properties and special structures. Compared with ordinary wires and cables with a large quantity and a wide range, special cables have the characteristics of higher technical content, stricter use conditions, smaller batches, and higher added value. Special ... more

6 skills that must be mastered when laying outdoor cables The installation and construction of outdoor power cables is relatively difficult due to the complex terrain and numerous equipment and facilities in the urban area. In order to avoid problems such as cable abrasion, equipment damage, and personnel safety caused by construction, the following summarizes the 6 major techniques for laying outdoor power cables. 1. Before laying the cable, check whether the type and specification of the cable meet the design requirements: armore... more

The significance of measuring the insulation thickness of wires and cables 1.Standard value: The insulation thickness specified in the wire and cable product standard is based on the applicable voltage level of the product, the size of the conductor cross-section, the size of the current carrying capacity, the environmental conditions used, the electrical properties of the insulation material, the physical and mechanical properties, and the long-term consideration Many factors of the service life are determined through scientific ca... more

The connection and difference between the cable isolation sleeve and the inner lining In the production and manufacturing process of cables, the two concepts of isolation sleeve and inner lining are often encountered. The so-called isolating sheath is the sheath between the coating layers of two different metal materials, which is commonly referred to as the inner sheath. The inner lining is the core and filler (if any) of the multi-core cable. The non-metallic cladding layer on the outside and under the protective layer. Isolation... more
