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.

技术特点/Technical characteristics：

1、公司产品外壳采用玻璃钢，玻璃钢是各向异性的材料，加上其配方和添加物等有广泛的选择性，根据玻璃钢工作的环境和状态，添加了特制的阻燃添加剂，使玻璃钢材料有良好的阻燃性，试验结果如下：

The shell of products is made of glass fiber reinforced plastics, which is anisotropic material. Besides, the formula and additives are widely selected, according to the working environment and state of glass fiber reinforced plastics, special flame retardant additives are added to make the glass fiber reinforced plastics have good flame retardant property. The test results are as follows:

玻璃钢属复合材料，它对酸、碱、盐、油等各种腐蚀介质都有特殊的防止功能，且不会发生锈蚀。满足沿海地区和化工场所及长期直埋地下的要求。产品性能保证附件产品能够长时间稳定运行。  FRP is a high-quality composite material, it has a special function to prevent acid, alkali, salt, oil and other corrosive media, and will not rust. Meet the requirements of coastal areas, chemical sites and long-term direct buried underground. The product performance ensures that the accessory products can run stably for a long time.

2、在防爆壳的结合部分采用硅橡胶密封圈对壳体进行密封，增强电缆中间接头的防水性能。

Silicone rubber sealing ring is used in the joint part of the explosion-proof shell to seal the shell and enhance the waterproof performance of the cable intermediate joint.

3、具有很强的耐压性能，壳体可以承受来自内部或外部的超强冲击。

The shell can withstand the strong impact from inside or outside.

4、安装方便快捷，可以满足110kv、220kv单芯电缆敷设要求。

Easy and fast installation, can meet the 110kV, 220kV single core cable laying requirements.

5、安全可靠，广泛适用于电力、煤炭、化工等各种高危行业及重点工程的供电网络。

Safe and reliable, widely used in power, coal, chemical and other high-risk industries and key projects power supply network.   

安装说明如下Installation instructions are as follows：

1.准备工作/Preparation

1.1检查所配玻璃钢外壳适用的规格和尺寸与电缆的外径和中间头的配合尺寸是否吻合；

Check the applicable specifications and dimensions of the FRP housing to see if consistent with the outside diameter of the cable and the matching size of the middle head.

1.2检查玻璃钢外壳的密封材料(哈呋开口的密封垫，玻璃钢外壳两端口与电缆的密封材料：带材)是否充足；

Check whether the sealing material of the FRP housing (Hafuran open gasket, FRP housing two ends and cable sealing material: strip) is sufficient

1.3检查高压电缆密封胶两组份电缆胶包装是否完整，组份的数量是否充足；

Check whether the packing of the two-component cable sealant is complete and the quantity of the components is sufficient;

2.玻璃钢外壳的装配/Assembly of FRP housing

对待安装的玻璃钢外壳的中间接头段清洁处理，装上玻璃钢外壳的上下半，引出同轴电缆或接地电缆，上紧若干个螺栓，防爆盒两端口和同轴电缆或接地电缆必须先做密封处理(包防水密封带材)；

The intermediate connector section of the installed FRP shell shall be cleaned, the upper and lower half of the FRP shell shall be installed, coaxial cable or ground cable shall be drawn out, and a number of bolts shall be tightened. The two ports of the explosion-proof box and coaxial cable or ground cable shall be sealed first (waterproof sealing strip).

2.1拿一个干净的桶，将两组份高压电缆密封(AB胶）倒在干净的桶中，合在一起用电动搅拌机搅拌均匀；

Take a clean bucket, pour the two-component high voltage cable seal (AB glue) into the bucket and mix together with an electric mixer;

2.2灌胶：灌胶要注意它的连续性，每组胶灌入的间隔的时间越短越好；灌胶时请注意漏胶；

注意：高压电缆密封胶的双组份电缆胶在其固化过程中略有些体积膨胀，所以不能灌的太满，一般灌到低于灌胶口上沿20至30mm的高度；

Glue filling: the continuity of glue filling should be paid attention, the shorter the time interval between each group of glue filling, the better; Please pay attention to glue leakage when filling;

Note: the two-component cable glue of the high-voltage cable sealant has a little volume expansion during its curing process, so it should not be filled to a height of 20 to 30mm lower than the top edge of the sealant.

3.封盖口，安装完毕。
