6Screen adopts double-deck tin plated wire braid, and density reaches 98.5%, prevents the interference of electromagnetic field effectively; Restrictive coating adopts flame-retardant low-smoke halogen-free flexible polyolefin material, and the fire resistant flame retardant performance is arranged.
Adopting two specifications is 1.0mm
2Power line 2, power line is that tinned wird good with corrosion resistance, good welding performance is a conductor; The polyolefin material of fire-retardant, the low cigarette of insulating barrier employing, Halogen, softness has the fire resistant flame retardant performance.
Adopting four specifications is 0.5mm
2Audio frequency control line 3, audio frequency control line 3 is that tinned wird good with corrosion resistance, good welding performance is a conductor; The polyolefin material of fire-retardant, the low cigarette of insulating barrier employing, Halogen, softness has the fire resistant flame retardant performance.
Experiment shows that the every performance index of the utility model can reach: operating voltage is 600V and following; Operating ambient temperature is-45 ℃～+ 150 ℃; Through-put power, transmission of video and audio frequency are stable, and be undistorted, and decay is no more than 0.28dB/m; Have fire-retardant, wear-resisting, weatherability, bearing capacity is strong, safe and reliable; Volume is little, in light weight, soft, is applicable to length and lays apart from installing.
