Composition of flexible mineral insulated cable (bbtrz)

Flexible mineral insulated acsr cable is composed of copper strand, mineral compound insulation and mineral compound sheath. It adopts flexible structure, and the main materials are inorganic materials, which make up for the defects of hard structure, easy to burn and toxic. It also has some advantages that other cables can not have, such as: … Read more

Is the diameter of copper wire less than the national standard a non-standard cable?

For a long time, there is a headache for aaac cable sales, that is, whether the loss of square cable is non-standard cable. Because many customers like to measure the diameter of cable conductor, it can be used to determine whether the cable is qualified. So many people discuss, is copper wire diameter smaller than … Read more

Tips for ACSR cable fault location

The occurrence of ACSR Cable 336.4 MCM  faults is accompanied by the laying and use of cables. The location of cable faults varies with cable laying methods, and the difficulty in locating is gradually increasing. Among them, the positioning and searching of bridges, tunnels, and trenches are relatively simple, while the direct-buried method is the … Read more

Comprehensive performance comparison of copper and copper clad aluminum wire

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

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

Cable Quality Defects and Their Elimination Methods

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

Plastic Extrusion and Traction Speed of Cable Technology

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
