? ?电力是当今社会生产生活的主要动力来源，随着当今城市规模不断扩大以及现代化生产程度日趋提高，输供电系统呈现出：供电网络庞大，供电系统复杂，供电环节多，供电距离长等特点。电缆中间接头作为整个供电网络的重要接续点，其运行稳定性将直接影响到供电系统的运行质量，由于电缆中间接头是由人工在现场安装完成的，受到施工环境和运行环境的影响，不可避免的会因为安装失误、外力破坏、电缆进水等原因造成击穿和爆炸事故。而且在电缆接头发生击穿和爆炸事故时会释放出大量的能量，对周边其它电力设施或人员造成危害，甚至会造成二次事故的发生，针对这些问题，上海朋源电气设备有限公司研制开发了具有防火、防水、防爆作用的电缆中间接头盒，进行全方位防护，一旦电缆中间接头发生爆炸或击穿，可以对周边其他电力设施以及人员进行有效的保护，防止二次伤害的发生。

Electric power is the main power source of production and life in today&＃39;s society. With the continuous expansion of urban scale and the increasing level of modern production. The power supply system presents: huge power supply network, complex power supply system, many power supply links, Long power supply distance and etc. Cable intermediate joint as important connection point of the whole power supply network, the operation stability will directly affect the running quality of power supply system, due to the cable intermediate joint is completed by manual installation at the scene, Under the influence of construction environment and operation environment, breakdown and explosion accidents will inevitably occur due to installation error, external damage, cable water inlet and other reasons. In addition, a large amount of energy will be released when the cable joint breaks down and explodes, which will cause harm to other surrounding power facilities or personnel, and even cause the occurrence of secondary accidents,?aiming at these problems,?Shanghai friends source electrical equipment Co Ltd.?has developed the cable intermediate connector box with the functions of fire prevention, waterproofing and explosion-proof, which can carry out all-round protection. In case of explosion or breakdown of the cable intermediate connector, it can effectively protect the surrounding power facilities and personnel and prevent the occurrence of secondary damage.
