1. The main cable conductor has no joints and the joint structure of branch line of cable conductor is reasonably designed, contacting resistance is very small, so it is never influenced by expanding with heat and contracting with cold.
2. The cable has excellent properties of anti-vibration, fine gas-proof and waterproof, so it can be used for normal power supply in wet environment and be laid in open air or underground.
3. The cable occupies a small area, so it can be effectively used at construction site and also easy for installation.
