Construction method: 1. Place the heat shrinkable cable cap on the end of the steel pipe, remove the foam powder and double-walled heat shrinkable tube except rust to the ST3 level, where the oil is used Shab wipe clean. 2. Clean the hair of the head of the Heat shrinkable cable cap with the overlap of the jacket. 3. Preheat the steel pipe and the hairy jacket part. (The preheating temperature should reach 50 ℃ without affecting the original anticorrosive layer). 4. Put the heat shrinkable cable cap into 5. With the heater to the hot shrinkage cable cap head does not cycle evenly heating shrinkage, until the hot melt glue overflow. (If the temperature is high, there is a slip when heating the small head, and the wet towel can be covered above). 6. The end of the Heat shrinkable cable seal (and the foam attachment) shall not be overheated. 7. Heat the hot shrinkage Cable seal cap of the small head to the hot melt glue overflow. When the shrinkage is complete, roll the waterproof cap with a press stick. 8. After the completion of construction should be no bubbles, no surface carbonization phenomenon and obvious folds, all edges have glue overflow, bonding firm.

Cable cladding is often referred to as cable patches, zipper type heat shrinkable tubes, open heat shrinkable tubes, this product is mainly used to repair cables and cables high temperature heat shrinkage tube sleeve breakage, can be simple and rapid to the damaged cable outside the sheath sealed and insulated. It is a coated sheath repair casing, simple construction, wide range of dimensional selectivity, all kinds of occasions applicable, with hot melt adhesive can solve the problem of sealing waterproof, insulation can reach the complete cable insulation level.

Cable cladding Use Range: 35kV and the following single-core cable, two-core, three-core, four-core, five-core power cable sheath repair and sealing insulation. Communication cable HYA Market Line, a variety of caliber local cable, radio and television signal transmission cable, telecommunications cable sheath breakage repair. Breakage repair of railway signal cables, sheath repair of mining cables and other sheath cables that need to be repaired.

Cable cladding use: Cable cladding is mainly used for high and low voltage power cables, communication cables, communication optical cables and CATV cable/cable skin breakage repair. When the underground cable ditch space is small, it can also be used as an outer sheath connected to the middle of the cable.

FEP热缩管热缩电缆封帽及电缆包覆片的作用

FEP热缩管特点：高阻燃、韧性好，优异的物理性能和耐化学腐蚀性能，不含氯化合物PCBS、PCPS及多溴联苯PBBs、多溴氧化联苯PBBOs、多溴联苯醚PBBEs、PBDEs等对环境有害的物质，符合SGS环保指令。

FEP(聚全氟乙丙烯)收缩比1.3：1，PTFE聚四氟乙烯（）收缩比1.7:1，耐温260℃，FEP基本保留PTFE多种特性，但在耐高温200℃，比PTFE低60℃。由于FEP具有较低的熔融粘度和优异的热稳定性，因此可像其他热可塑性产品一样，能使用挤压、传递、注射、压缩，吹塑成型方法以加工。FEP的透明度高，PTFE没有FEP的高透明。

FEP热缩管适用范围：航空航天、仪器仪表、轻纺化热缩管工、食品医疗、电子电器、邮电通信、石油化工、冶金电子、铁道交通、电机电器、家用电器、高层建筑、灯饰照明、特种变压器、特种电缆、传感器、热敏元件等行业。

规格：最小做到收缩后Ф1.5内径，最大做到收缩后Ф200内径，壁厚做到0.1-2.5mm。

热缩电缆封帽,也热缩封帽，电缆封帽，热缩防水帽，它是一种经高能离子辐射处理的聚乙烯材料，外观呈帽状，由聚乙烯管材扩张成型后覆合一层热熔胶膜而成，热缩电缆封帽具有较高的机械强度，耐老化性，耐环境应力开裂、密封性能好等特点，具有较长的使用寿命，该产品适用于各种规格的聚氨酯泡沫塑料保温管端头防水和防护。
