Transparent heat shrinkable tube is an important equipment for cable connection and grounding sealing in various industries, especially for some cable connection devices with high sealing performance. The structure, raw materials, materials and performance directly affect power loss and cable connection. At present, the cable connection mainly has the traditional post-welding protection process. The traditional welding plus protection method can ensure the welding effect, but it is time-consuming and labor-intensive, and factors such as poor sealing effect will directly affect the use of cables and energy loss. In order to overcome the poor sealing performance and welding problems of the existing transparent heat shrinkable tubes, technicians developed a simple structure, good sealing effect, good shielding effect, long service life, safe

　　In order to overcome the poor sealing performance and welding problems of the existing transparent heat-shrinkable tubes, technicians have developed and provided a transparent heat-shrinkable tube with simple structure, good sealing effect, good shielding effect, long service life, safety and reliability. The technical solution adopted by the transparent heat-shrinkable tube is a heat-shrinkable tube, and a rubber ring and a tin ring are set in the middle of the heat-shrinkable tube, and rubber rings are arranged on both sides of the tin ring for sealing. The adhesive rings on both sides are made of raw materials with the same shrinkage rate, and the shrinkage rate of the adhesive ring is different from that of the heat shrinkable tube. There is also a branch line connected to the tin ring in the heat shrinkable tube, and the branch line is grounded. The transparent heat-shrinkable tube is made of fluoroplastic heat-shrinkable tube, and the heat-shrinkable tube is covered with a left rubber ring, a right rubber ring and a tin ring, and the tin ring is located in the middle of the left rubber ring and the right rubber ring. There are left rubber rings and right rubber rings on both sides of the tin ring to seal, which can prevent the solder from flowing out under high temperature heat shrinkage and protect the internal cables. The heat-shrinkable tube also wraps the sub-wire, and one end of the cable is connected to the tin ring, and the other end is grounded to act as a barrier. When in use, the heat-shrinkable tube is tightly fixed on the protected cable after being baked at high temperature, and the rubber rings at both ends play a role of protection and sealing to prevent air, water vapor, etc. The ring is melted and coated on the surface of the connected cables, welding the cables tightly together.
　　The structure of the transparent heat-shrinkable tube is simple and reasonable. Both sides of the heat-shrinkable tube are designed with a double rubber ring sealing structure, which provides double guarantees for the sealing of the cable connection and ensures the heat-shrinkage effect of the cable connection in harsh environments such as high temperature and high humidity. In addition, the tin ring joint of the transparent heat-shrinkable tube is connected to the grounding wire, which completes the sealing protection of the cable and also realizes the grounding, ensuring the same structure of the equipotential body. The transparent heat-shrinkable tube adopts fluoroplastic heat-shrinkable tube, which is transparent, flame-retardant, high-temperature resistant, oil-resistant, corrosion-resistant, and wear-resistant. It solves the above-mentioned problems such as time-consuming, labor-intensive, and poor welding.
