Advantages:
1. Easy maintenance: line capacity is strong, simple in line.
2. High strength, trampling resistance, impact resistance, prevent short-circuit.
3. Sting threading pipe construction anti interference, signal shielding,to prevent the mutual interference between strong and weak electricity.
4. Safety: the safety of grounding and electric leakage protection appliances and timely.
5. Flame retardant: line to prevent burning when short circuit occurs.
6. Environmental protection: can be recycled, avoid secondary pollution.
7.High carrying capacity: under the condition of the same wire diameter passing rate is high;current circuit long life.
