power cable As an important part of power system, it is widely used in various power transmission and distribution occasions. According to different voltage levels and insulation conditions Cable It can be divided into several types, each of which has its unique characteristics and application scenarios.
1、 Definition and main characteristics
Rubber cable is mainly made of rubber Insulating material Because of its good flexibility, abrasion resistance, oil resistance and other characteristics, the cable products are widely used in electric power, coal mine, steel and other fields. Compared to other Cable products and rubber cables have the following main characteristics: 1. Good flexibility: As an insulating material, rubber has good flexibility and can be used under small bending radius, which is convenient for laying and wiring.
2. Strong abrasion resistance: rubber has good abrasion resistance and can be used for a long time under friction and occasions.
3. Good oil resistance: the insulation material of rubber cable can effectively prevent oil pollution and can be used in the environment with serious oil pollution.
2、 Classification
Rubber cables can be divided into the following categories according to their use and structure:
1. Rubber cable for electric power: It is used for power transmission and is widely used in power stations, substations, factories, mines and other places.
2. Rubber cable for control: It is used to transmit control signals and is widely used in machines, electrical appliances, instrumentation, etc.
three Electric welding Machine rubber cable: used for power input of electric welding machine. It is one of the commonly used cables for electric welding machine because of its high temperature resistance, abrasion resistance and bending resistance. 4. Mobile rubber cable: It is used for power and signal transmission of mobile machinery and equipment, and has been applied in various environments such as mines, docks and construction sites.
3、 Advantages and precautions
Rubber cable has the following advantages:
1. Good wear resistance, oil resistance and other properties, suitable for use in harsh environments;
2. Good flame retardancy, safe and reliable use;
3. It has good flexibility and bending resistance, and is convenient for wiring and maintenance.
In the process of using rubber cables, the following items should be noted:
1. Avoid excessive pulling and bending to avoid cable damage;
2. Conduct regular inspection and maintenance to avoid cable aging and failure;
3. When using rubber cables, relevant national and industrial regulations and standards shall be observed to ensure safety and reliability.
