Control cable shields How to install: metallic shield and shield grounded metal shield is weakened and an important measure to prevent electrical interference, including wire core shield, shielding, and the two-tier total shielding. Measures to control the cable metal shield type selection, the strength of electrical interference shall be possible, included in the integrated interference suppression to meet to reduce interference and over-voltage. On the anti-jamming effect of the higher requirements, the corresponding investment greater, when using steel armor, steel wire braided shield when the price of the cable increased by about 10% to 20%. Strong electric loop control interference signals due to its strong, so in addition to ultra-high pressure distribution equipment located in or close to parallel with the high voltage cable is longer, but can be selected without a metal shield control cable. When weak signal control loop control cables used, when in the presence of interference in the environment, do not have effective anti-jamming measures, should use a metal shield control cable to prevent electrical interference with low signal circuit malfunction or to insulation breakdown and other effects. Weak loop control cables if they can pull enough distance from power cables, or laying pipe, it may cause the external electrical interference is reduced to allowable limits. Control cable, which models: high-temperature control cable (KFF cable) applicable to the exchange rated voltage 300/500 and below, high temperature signal detection. Especially for the protection of transmission lines and power control circuit in the fire and security systems. Use features: Operating temperature: 200 ℃ long-term use of short-term use 1000 ℃ 90 minutes.
