Why are shielded cables woven with tinned copper wire?
Flame retardant flexible cable for DC cable communication power supply is flame retardant flexible cable used in power supply and distribution system of Communication Office (station) and high-rise building power supply.
The long-term allowable working temperature of the cable conductor is 70 degrees centigrade, and the cable laying temperature shall be no less than 0 DEG C. Allowable bending radius of cable: the cable with armored or copper tape shielding structure shall be no less than 12 times of the cable outer diameter. For flexible cables with shielding layer, the cable shall be no less than 6 times of the outer diameter of the cable. The cable with no armour shall be no less than 6 times the total diameter of the cable.
Tinned copper is used to increase strength and avoid oxidation and corrosion of copper. Improve solderability and reliability. Another thing is that tin looks better.
