The use and characteristics of rubber insulated wire and cables


Rubber insulated wire is one of our commonly used power cables. Its conductor is composed of multiple strands of thin copper wire, and the outer layer is mainly a soft and movable cable type with rubber insulation and rubber sheath. What are the types of rubber sheathed cables, what are their uses and what are the principles for selecting types? Let's have a chat! ! !

What is a rubber sheathed cable?

 

The conductive core of the rubber sheath cable is composed of multiple single copper wires, and its external insulation is made of rubber insulation and rubber sheath. Rubber-sheathed cables generally include general-purpose rubber-sheathed soft cables, electric welding machine cables, submersible motor cables, wireless device cables, and photographic light source cables.

 

The use of rubber insulated wire and cables

 

Rubber insulated wire and cables are widely used in various electrical equipment, such as mobile power cords for household appliances, electric machinery, electrical equipment and appliances, and can work under indoor or outdoor environmental conditions. According to the external mechanical force of the cable, the product structure is divided into three categories: light, medium and heavy.

Lightweight (YQ): Generally suitable for household appliances and small electric equipment, requiring softness, lightness, and good bendability.

Medium (YC): In addition to industrial use, it is widely used in agricultural electrification.

Heavy-duty (YZ): It is mostly used in port machinery, searchlights, large-scale agricultural irrigation and drainage stations, etc. This type of cable has good versatility, complete specifications, good and stable performance.

Rubber insulated wire and cables features:

 

1. It has incomparable flexibility with other wires and cables;

2. Excellent electrical insulation performance and chemical stability;

3. Good physical and mechanical properties and wear resistance;

4. Performance requirements such as oil resistance, flame retardancy, wall resistance, and heat resistance.

 

How to choose rubber insulated wire and cables?

 

Rubber insulated wire and cables are used in lines with a voltage of 220/380V. YC heavy-duty general-purpose rubber-sheathed cables are suitable for household appliances, electric tools, and various mobile electrical equipment or light mobile electrical equipment with AC rated voltage below 450/750V, or for It is used for temporary construction on the construction site and can withstand large mechanical external forces. The long-term allowable operating temperature of the wire core should not exceed 60°C.

1. To choose the variety of rubber sheathed cable, you need to understand the performance indicators of all aspects of the cable in detail. For some conditions such as the wear resistance, compression resistance and service life of the rubber sheathed cable, conduct detailed inquiries and understand, and then judge whether it is in line with your own use conditions match. And whether there is a national compulsory certification mark after the cable production is completed, and whether the company has a corresponding quality assurance certificate, etc. the

2. The influence of the surrounding environment on the use of the cable During the use of the cable, in addition to being limited by its own use conditions, there are also some external environments that play a decisive factor on it, such as: if there is interference from the magnetic field, then the cable needs to be added. There is a shielding layer; if it is a welding robot, due to the long working time and high temperature, it will have a great test on the outer sheath of the cable, so the selection should be made according to the actual situation.

3. Clarify the use function of the cable Whether it is a control cable or a rubber sheathed cable, no matter how excellent the performance of the cable is, what we have to do is to install the cable in a position suitable for its use. Only in this way can the original quality of the cable be achieved. It has excellent performance and service life.

In the wire and cable production process, wire and cable manufacturers strictly control the details of each production to ensure the high-quality display of products, always focus on production and use safety, and provide customers with the safest and most reliable product services.
