RVVP copper wire woven shield, how to calculate how much copper wire weaving, weaving density calculation?
Allowable bending radius of cable: the cable with armored or copper tape shielding structure shall be no less than one or two times of the cable outer diameter. For flexible cables with shielding layer, the cable shall be no less than that of the outer diameter of the cable. The cables without armour layer shall be no less than the land diameter of the cable outer diameter. 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
Heat resistance and mechanical strength. 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. Tin shielded control cable features: the conductor conductor long-term allowable temperature is 0 degrees, the temperature of cable laying shall be no less than 0 degrees centigrade.
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.
