1. Internal conductor use international standard round copper(No.1 electrolytic copper smelted by CYMG ) strictly.Isolation by high pressure process polyethylene.The characters are as follows: low reduction, good moistureproof, small radius curve, etc.

2. Cryptographic knit and Aluminum longitudinally covered make higher shield, especially for long-distance transmission. Four shielding access cables together with Argon arc welding aluminum tube lines much more suitable for the HFC wide band.

3. The outer sheath has characters as high antiflaming, anti-aging, moistureproof, and good support performance, which insure long service life of cable.
