The sustained and rapid growth of China’s economy provides a huge market space for cable products. The strong attraction of the Chinese market has led the world to focus on the Chinese market. In the short period of reform and opening up, China’s cable manufacturing industry The huge production capacity created makes the world impressive. With the continuous expansion of China's power industry, data communication industry, urban rail transit industry, automobile industry and shipbuilding industry, the demand for wire and cable will also grow rapidly. The wire and cable industry in the future will have enormous potential for development.
Rubber sheathed cables are widely used in a variety of electrical equipment, such as mobile power cords for household appliances, electrical machinery, electrical equipment and appliances. It can be used indoors or outdoors. According to the external mechanical force of the cable, the product structure is divided into three categories: light, medium and heavy. There is also proper convergence in the cross section.
General light rubber sheathed cables are used in daily-use electrical appliances and small-sized electrical appliances, and are required to be soft, lightweight, and have good bending performance;
Medium rubber cable is widely used in agricultural electrification except for industrial use;
Heavy-duty cables are used in applications such as port machinery, searchlights, and large-scale hydraulic irrigation and drainage stations in the home industry. This kind of product has good versatility, complete specifications, good performance and stability.
Precautions I. Equipment:
Compact pressure device with automatic temperature control, timing and multi-size tubular cavity.
Second, rubber:
It is consistent with the wire used to make up the wire, and contains more glue than the material being filled. The vulcanization system is slightly stronger.
Third, the operation method:
1. Set the temperature and time according to the vulcanization system of the rubber material. 2. Use a rubber ink thinner to wash the repaired area, especially the joint area.
3, according to the size of the gap to cut the amount of repair rubber, pay attention to not too much or too little,
4. Put the cut plastic material in the gap, and pay attention to that the rubber material should not be higher than the circumferential surface of the wire.
5, wrapped with high temperature PP tape. And put it in a tubular mold cavity slightly smaller than the wire diameter, and lock the upper and lower molds, so that the position to be filled with a certain pressure. Note that the cavity diameter is slightly smaller than the wire diameter by 0.1~0.2mm.
6, until the vulcanization time is reached, remove the product, if there is a small amount of rubber spills, use a sharp blade to complete, and dilute with a diluent.
Fourth, verification method:
Press the appropriate amount of air into the filled wire and place it in water.
Brief Analysis on Several Important Considerations of Rubber Cables
The wire and cable industry is China's second largest industry after the automotive industry, with product variety satisfaction rates and domestic market share exceeding 90%. In the world, China's total output value of wire and cable has surpassed that of the United States and has become the world's largest wire and cable producer. With the rapid development of China's wire and cable industry, the number of newly added companies has continued to rise, and the industry’s overall technological level has been greatly improved.
