Surface Quality
- Should be neat and well-distributed in dimension on surface of aluminum rod
- Aluminum rod surface should be clean and free from flaws, wrinkles, wrong round, crackle, mess kink and other shortcomings that affect usage
- Permissible: slightly mechanical rub speck, pit, losing leather or fing border
Application
Conductor (AAC and ACSR) have been widely used in power transmission lines with various voltage levels because they have such good characteristics as simple structure, convenient installation and maintenance, low cost, and large transmission capacity. They are also suitable for laying across rivers, valleys, and places with special geographical features.
