Waterproof cold shrink tube used in telecommunication joints
In the mid-1960s, 3M company invented the cold shrink material technology. In the late 1980s, the northern United States tried to apply cold shrink tubing to cable joints. In 1994, 3M cold-shrinkable materials entered the Chinese market. From 1998 to 2002, cold-shrinkable materials were recognized in the market and became the most popular new technology product in China.
Most of the cold shrinkable tubes are used for the sealing and protection of cable connections. In order to adapt to a wider range of applications, the silicone rubber cold shrinkable tubes developed by KEHONG Electronics have a high shrinkage ratio and can be used for the protection of large diameter cables. 40/9-180mm silicone rubber cold shrink tubing is very popular among Korean customers. We have customized a lot of white for customers, and equipped with 40/12-150mm heat-shrinkable cable gland tubing with middle wall rubber tubing.
However, during installation, if the installation personnel are not careful, the wrench will damage the surface of the silicone rubber cold shrinkable tube, and the cold shrinkable tube needs to be replaced at this time.
In order to solve this problem, in addition to the silicone rubber cold shrinkable tube, the technical research and development personnel of Kehong Electronics have also developed a cold shrinkable tube made of EPDM rubber material, that is, EPDM cold shrinkable tube, which has strong tear strength and tensile strength. Compared with silicone rubber cold shrink tubing, EPDM cold shrink tubing has better UV resistance. If it is used outdoors, EPDM cold shrink tubing is definitely an ideal choice.
Due to the requirements of cable and cable waterproof and sealing, Kehong Electronics has also developed cold-shrinkable cable accessories for supporting use.
防水冷缩管在电信行业的应用
在上世纪60年代中期，3M公司发明了冷收缩材料技术，上世纪80年代末，美国北部试图将冷缩管应用到电缆接头。1994年3M冷缩材料进入中国市场，1998年-2002年，冷缩材料在市场上得到了认可，成为中国最流行的新技术产品。
冷缩管大多数用于电缆连接的密封防护，为了适应更加广泛的应用，KEHONG 电子研制出的硅橡胶冷缩管，具有高收缩倍率，可用于大直径电缆的防护。40/9-180mm硅橡胶冷缩管备受韩国客户喜爱，我们给客户定做了大量白色，同时给配备了中壁含胶管40/12-150mm热缩电缆接头管。
但是在安装的时候，如果施工人员安装不仔细，扳手会伤害到硅橡胶冷缩管的表面，这个时间还需要更换冷缩管。
为了解决这个问题，除了硅橡胶冷缩管外，柯鸿电子公司技术研发人员还开发了三元乙丙橡胶材料的冷缩管，即EPDM冷缩管，撕裂强度和拉伸强度都很强，和硅橡胶冷缩管相比较，EPDM冷缩管的抗紫外线效果更好，如果是在户外使用，EPDM冷缩管绝对是理想的选择。
由于电缆电缆防水密封的要求，柯鸿电子公司还开发出了冷缩电缆附件来进行配套使用。
