Power Cables are divided into different inner conductors. There are two main types, one is pure copper material and the other is copper-clad aluminum material. The English name of copper-clad aluminum is Copper Clad Aluminum, so copper-clad aluminum conductors are also often called: CCA conductors. Copper-clad aluminum composite wire was first introduced by Germany in … Read more
1. Preparation of raw materials The preparation of raw materials requires warm glue and glue cutting. The weighing of raw materials is a crucial process of preparation. 2. Plasticizing Rubber has high elasticity at room temperature and is not easy to process. Therefore, it is necessary to change its high elasticity to make it have … Read more
Wire drawing process Pulling force is applied to the metal rod to pass through the die hole to obtain products with the same size and shape of the die hole. The plastic processing method standard drawing wire or wire drawing. 1. The main points of drawing round copper wire 1 When changing the appearance of … Read more
There are two key links in the wire and cable manufacturing industry, namely theAluminum conductors steel-reinforced production link and the wire and cable testing link, especially the wire and cable testing link. This is the last stop for quality control and a comprehensive assessment of the performance of wires and cables. The burning test of … Read more
The energy saving effect of frequency conversion device is very obvious, the use of frequency conversion speed regulating motor in high power motor, the whole generator set can save 30% electricity. And after the use of frequency conversion speed regulation, the soft start of the motor is realized, so that the motor works smoothly, the … Read more
The crosslinking degree (thermal elongation) is not acceptable If the crosslinking degree is not up to the standard, the thermal and mechanical properties of the cable are not qualified and can not meet the requirements of the working temperature of 90℃. The reasons for the unqualified crosslinking degree are as follows: first, the formula is … Read more
The rate of plastic extrusion According to the flow rate analysis of the viscous fluid in the material conveying and homogenizing section of the ABC conductor, the flow rate of the plastic (that is, the extrusion speed) is proportional to the screw speed, and the screw speed is an important operating variable to characterize the … Read more
Environmental protection wire refers to the material is environmental protection wire. The material includes insulating material, conductor material and shielding material. Insulation such as PVC, irradiated cross-linked PVC (XL-PVC), irradiated cross-linked polyethylene (XL-PE), low smoke free (Halogen-free), silicone rubber, Teflon Telflon and so on. The environmental protection of insulation materials is mainly the EU’s RoHS … Read more
