For example, coaxial cable and RVVP with shielding layer of many of the cables are tinned copper wire, what are the benefits?
1 wire, good toughness, good conductivity, good anti-interference.2, copper easy oxidation, tin oxidation.Gold can be, but the price is higher than steel.
Corrosion resistance, improve solderability and reliability
Tinned copper is used to increase strength and avoid oxidation and corrosion. Improve solderability and reliability. Another point is that it looks a little better.Tin shield control cable features:The allowable working temperature of the cable conductor is 70 DEG C, and the cable laying temperature shall not be less than 0 DEG C. Bending radius of cable is allowed: 12 times of armoured or copper tape screened cable should not be less than the outer diameter of cable. The flexible cable with shielding structure shall not be less than 6 times of the outside diameter of the cable. For non armoured cable should not be less than 6 times of cable diameter.Flame retardant flexible cable for DC cable communication power supply is a kind of flame retardant flexible cable for power supply and distribution system, which is suitable for power supply of Communication Bureau (station) and high-rise building.
