消极高屏蔽计算机电缆DJYPVRP苏尼特右旗In order to evaluate the flame-retardant performance of wire cables, iec 60332-1, iec 60332-2 and iec 60332-3 were formulated respectively. Iec60332-1 and iec60332-2 are respectively used to evaluate the flame retardant capability of a single cable when it is laid on an incline and vertically (corresponding to GB12666.3 and GB12666.4 in China). Iec60332-3 (domestic equivalent to gb12666.5-90) is used to evaluate the flame retardant capability of beam cable when it is vertical, compared with that of beam cable when it is vertical.
Electronic computer shielded cable, choose high pressure polyethylene insulation, small dielectric constant use to ground, and the screen, the total screen (or three quad twisted, group screening, group screen a total screen), such as structure, with a small dielectric loss, transmit ability strong, good anti-jamming performance characteristics, can be reliably transmitted weak the analog signal or digital signal, can be widely used in electricity, metallurgy, petroleum, chemical, textile and other departments of detection and control computer system or automated devices, as well as general industrial computer. High-temperature F46 computer cable belong to one of the special cable, electronic computer system is in urgent need of modern industrial construction of form a complete set of products, it is widely used in energy industry, metallurgical industry and petrochemical industry and other industrial enterprises and scientific research department of the electronic computer, instruments and meters, all kinds of automatic detection equipment, and other information processing equipment signalling and the control system. Application: it is installed in indoor, cable trench, pipe and other places where high temperature resistance electrostatic shielding is required
IEC/BS4066-1阻燃等级（单根电线或电缆垂直燃烧测试FlameTestONSingleVerticalInsulatedWires/Cables）这是单根电缆的阻燃标准。
IEC/BS4066-3阻燃等级（成束电线或电缆垂直燃烧测试FlameTestOnBunchedWires/Cables）这是成束电缆的阻燃标准。
Identification and length marking: there are permanent identification marks on the cable surface, and the marking interval is not more than 1m.

综合布线、安防工程、监控工程、弱电系统工程、银行监控、网络工程、音响工程、远程三表抄送、消防工程、楼宇防盗监控、门禁可视对讲等专用、音、视频电线电缆。
不同品牌的断路器，N标识的方向也不同——可能在左，也可能在右。
在购买断路器时，应购买N接线柱在同一侧的产品——一台配电箱内，不允许既出现左侧N接线柱的断路器，又出现右侧N接线柱的断路器。
接线时，将零线接到N接线柱上，无标识的接线柱接火线即可。
2P断路器和2P漏电断路器，理论上来说不需要区分零火线——左侧接零线或右侧接零线均可。
但如果按照规范操作，则应该参考同一个配电箱内的1P漏电开关和1P+N开关的N接线柱方向，保证2P断路器和2P漏电断路器的零火线顺序与1P+N和1P漏电断路器的零火线顺序相同。
