Computer shielded cable; Purpose: high voltage insulation with small interface constant. Use to ground, and the screen, the total screen (or three quad twisted, group screening, group screen a total screen), such as structure form, with a small dielectric loss, the transmission ability is strong, resistant performance is good wait for a characteristic, can reliable transmission weak analog or digital, can be widely used in electricity, metallurgy, petroleum, chemical, textile sites detection and control of the door or by computer automation instrumentation, and general industrial computer. Relevant technical indicators: reference BS5308 IEC189 and British second, product code 1 and code the DJ - (series code) electronic computer shielded cable Y - (insulation code) high-pressure polyethylene F - (insulation code) fluoroplastic V - (sheath code) polyvinyl chloride (R - said many strands of soft wire core P - (block code) copper mesh shielding P1 tin plated copper mesh shielding P2 copper tape screened P3 aluminum-plastic composite membrane shielding for example 1:3, product specifications order 7 (14) to 1.0 was computer shielded cable can be represented as: (1) total shielding DJYVP7 * 2 * 1.0mm2 (2) partial shielding multiple strands of soft line DJYPVR7 * 2 * 1.0mm2 (3) total shielding type DJYPVP7 * 2 * 1.0mm2 Type (1) packet shielding DJYPV3 x 3 x 0.75 was (group 2) screen a total screen DJYPVP3 x 3 x 0.75 was three, model name and use range model name using range DJYVPDJYPVDJYPVP total shielding polyvinyl chloride polyethylene insulating sheath computer cable shielding polyvinyl chloride polyethylene insulation group sheathed electronic computer cable shielding total shielding polyvinyl chloride polyethylene insulation group sheathed electronic computer cable 1, fixed for laying indoors, in cable trench or pipe 2, cable long-term working temperature: - 20 ℃ + 65 ℃, the cable laying temperature is lower than 0 ℃, the bending radius should not less than 10 times of cable diameter DJYVPR DJYPVR DJYPVRP total shielding polyvinyl chloride polyethylene insulating sheath computer with a soft cable shielding polyvinyl chloride polyethylene insulation group sheathed computer with a soft cable shielding total shielding polyvinyl chloride polyethylene insulation group with a soft cable sheath computers shows that: (1) flame retardant cable (oxygen index greater than 30) need to add code "out" in front of the model. For example, zr-djypv zr-djypvp et al. (2) armored (steel belt armored) cables need to add code "22" in the lower right corner of the model, such as: DJYPV22 djypvpppvp22, etc. The cable is mainly used for ac or dc 300V or below and can work normally when 500V or below.



　　小弯曲半径:无铠装电缆应不小于电缆外径的6倍;有铠装电缆应不小于电缆外径的12倍℃。三、BV电线BV线用途一般用途单芯硬导体无护套电缆，适用于交流电压450/750V及以下动力装置、日用电器、仪表及电信设备用的电缆电线。

，我们常用的2.5平方电线，它的大载流量为I=2.5×6=15。要计算大承载功率，这与工作电压有关。如果是~220V电压、纯阻性负载，其大承载功率为P=220×15=3300(W)。电线粗细的选取不仅要考虑大载流量是否安全，会不会发热。还要考滤电压降是否允许。举两个实例，从电力机房到程控交换机机房，-48V(DC)供电，如果按电线载流量算，120mm足够，电线也不会发热，也很安全。

Local cable USES manufacuring HYA, HYAT, HYAC, HYPAT, HYPA and HYA53 HYAT53, HYPA53 HYPAT53 type cable is designed for main telephone switching area, relay telephone cable, manufacuring HYA, HYAT, HYPA and HYPAT is mainly used for pipe laying, also can be used for overhead, but need to disconnect; HYAC only applies to overhead, no need for suspension lines or hooks; The HYA53, HYPA53, and HYPAT53 cables provide the mechanical strength and corrosion resistance of the cables. They can be laid in any way, which is more suitable for direct burial in rock areas. The operating temperature is -30 ~60 degrees.
