The insulation material of wire and cable is an important structure to ensure the proper operation of the conductor. The operating life of the insulation material is an important indicator of the life of the cable. Usually, what are the insulation materials we use for wire and cable?

The Principle And Role Of A High-Voltage Line Arrester?
(1) The Role Of High-Voltage Line Arrester
High-voltage line arrester for 6 ~ 220kV AC transmission lines, is a new type of lightning arrester suspended and installed on the transmission tower.
Types Of High Voltage Power Cable Joints
In the case of high-voltage transmission line construction, many people working on projects often come across high-voltage power cable joints. Today, I would like to discuss the types of high voltage power cable joints and their applications with you. First, let’s talk about what high voltage power cable joints are.
Introduction to Flame Retardant Heat Shrink Tubing
The main role of heat shrink tubing in a circuit is to protect important devices and circuits from damage and impact. Although it does not have any particular impact on the operation of the circuit, it is often the key point that determines the success or failure of the entire design. With the rapid development of the electronics industry, flame-retardant heat shrink tubing is also inseparable from the electronics industry, more and more electronic products need to use flame retardant heat shrink tubing for protection. The flame retardant processing of the heat shrink tube, when attacked by external fire sources, can effectively block, delay or stop the transmission of flame, to achieve the effect of flame retardant.
Aluminum Conductor Composite Core Cable (ACCC) Advantage Introduction
At present, overhead cables are used to transport electricity over long distances. Conventional cables are mostly aluminum conductor steel reinforced (ACSR). Since the 1990s, carbon fiber composite cores (aluminum conductor composite core) have been used as the core bar of cables. ACCC has the following advantages over traditional conductors.
What Do I Need to Pay Attention to When Preheating Wire and Cable Conductors?
Wire and cable are used to transmit electrical (magnetic) energy. Information and the realization of electromagnetic energy conversion of wire products. Broadly speaking, wire and cable are also referred to as cable, and narrowly speaking, cable refers to insulated cable. It can be defined as a collection of the following parts: one or more insulated wire cores, and they may have their cladding, total protective layer, and outer sheath, the cable can also have additional conductors without insulation.
White Ceramics On Power Poles—Electrical Insulators
The main role of electrical insulators is to provide mechanical fixation and electrical insulation for electrical equipment and conductors in power transmission and supply lines. Insulators are currently available in three main materials, namely ceramic, tempered glass, and organic composite materials. Insulators have played an important role in the development of the electric power industry.
How to Use The Terminal Block
The wiring terminal is used to facilitate the connection of wires. It is a metal sheet sealed in insulating plastic. There are holes at both ends to insert wires, and screws are used for fastening or loosening. For example, two wires sometimes need to be connected and sometimes need to be disconnected. At this time, they can be connected with terminals and disconnected at any time, It is convenient and fast without welding or winding them together.
Factors Affecting the Insulation Resistance of Wire and Cable Products
The insulation resistance of wire and cable products mainly measures the volume resistance of the cable insulation layer, the surface resistance cannot be measured, and more factors affect the value of cable insulation resistance. In practical application, there are four main factors on the insulation resistance coefficient.
Tips for improving the overall performance of aluminum stranded wire with aluminum alloy core
The rated breaking force of the conductor is calculated based on the strength of all the aluminum single wires and reinforcements. However, the actual braking force deviates from the true calculated value. The main reason for this is that the strength of every single wire is not fully utilized. Therefore, when designing the product not only to meet its minimum strength requirements but also to consider how the strength of every single wire is tapped out. Not only is it a full use of the material, but the overall performance of the wire will also be greatly improved.
