What are the differences between the shielding layer of the control cable, the copper wire braid and the tinned copper wire braid?
Tin shield control cable features: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.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.
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.
Control cable shield layer, copper wire woven and tinned copper wire woven is different from tin plated copper wire woven insulation layer, the role is to prevent the current leakage along the radial, ensure the use of safety, has good electrical insulation performance. Heat resistance and mechanical strength.
