What is power transmission and transformation?

The transmission of current often leads to loss due to the heat of the line, so the voltage is increased through transformers during transmission, so that the current becomes smaller to reduce heat loss. High-voltage electricity is very dangerous, and the target electrical appliances do not need such a high [...]

AWG standard wire diameter comparison table

The thickness of the wire diameter is expressed by number (xxAWG). The smaller the number, the thicker the wire diameter and the greater the current it can carry. Otherwise, the thinner the wire diameter, the smaller the current resistance. For example: No. 12 has a current resistance of 20 amperes [...]

How to distinguish new raw materials and reworked plastic material

Plastic is a polymer material. The molecular weight of the new material is theoretically reduced by 30% after one use, which means that the various properties of the material are reduced by 30%. When the recycled material is recycled, some additives will be added, and various properties will be improved. [...]

What is the difference between OPGW and ADSS hardware?

OPGW cable and ADSS cable are completely different in structure, so they should be different in hardware. (1) Compared with ADSS, OPGW hardware requires higher slip strength and vertical load, so OPGW preformed rods for tension and suspension purposes needs higher strength, longer strand length and greater diameter than ADSS [...]
