3M Cold shrink terminal Connector , convenient installation 3M With the unique cold shrink technology, there is no need for special training, no need to push, fire and use special tools. All you have to do is gently pull out the core rope. Each set of terminals is packaged separately and is equipped with installation instructions. Wide application, one model is applicable to many Cable Wire diameter, single compact design, shorten the space distance. Reliable performance, applicable silicon rubber Material, strong resistance to electric trace and corrosion, good electrical performance, long service life. The rubber elastomer material is used to closely attach the cable body, which is moisture-proof and "breathes" with the cable. High dielectric constant stress control, reduce surface electrical stress.
● Cold shrink technology
As we all know, elastic rubber materials have " Elastic memory " Characteristics, like Spring 。 The cold shrink www.phxxkj.cn technology is also known as pre expansion technology, that is, the molded rubber parts are pre stretched in their elastic range by mechanical means, and then inserted into the plastic wire core for fixation. During installation, just pull out the wire core, and the elastic rubber body will shrink quickly and be tightly bound to the required installation position. 3M In the 1960s, the Power Products Department was the first in the world to invent the cold shrink technology and apply it to power cable The accessory industry and communication industry are widely welcomed by users because of their ease of use, safety and reliability. 3M Not only stay in invention, but also continue to innovate on this basis, and expand the application field to provide customers with high-quality and reliable power products and perfect services.
● Features of cold shrinkable power cable terminal
one Convenient installation
Using cold shrink technology , No need for hot work and special tools , There is no need to insert them piece by piece. Just gently extract the core rope. The constant force spring is used for grounding. No welding or copper binding is required. The construction saves time, labor and space. It is especially suitable for places with narrow construction space. Each set of products is packaged separately , Both are equipped with installation instructions and component lists with illustrations 。 two Wide application 3M When making the cold shrink cable terminal head, the pre expansion technology is used, so each specification can be applicable to a variety of cable diameters, and has strong compatibility with cable diameters. In terms of structure, the cold shrinkable cable terminal is of overall prefabricated compact design, and the electric stress control pipe, external insulation protection pipe and rain skirt are integrated. up to now, 3M The company already owns 35KV Complete series of indoor and outdoor cold shrinkable cable terminals up to and including, suitable for polyethylene cable, cross-linked polyethylene cable and ethylene propylene rubber cable
Etc. three Reliable Performance 3M The dielectric constant is twenty-five Of Hi-K The dielectric constant, dielectric strength, insulation resistance and dielectric loss factor of the material remain stable for a long time. Through this stress control method, the high electric field strength on the terminal surface can be reduced to 15V/mil Within the safety range of, the high potential moves to the end of the cable, rather than concentrating near the cable shield cut-off point, so that the distribution of the external insulation electric field of the cable terminal tends to be divergent and uniform. Therefore, the discharge voltage of the external insulation is increased, and the diameter of the entire cable terminal is reduced, and the shape coefficient is increased, which also improves the discharge voltage.
3M The external insulation material of cold shrinkable cable terminal is high-quality silicone rubber material, which has good hydrophobic performance. Water drops roll off at any time on it, do not form a conductive water film, and has hydrophobic self-healing performance. In addition, it has strong insulation, resistance to electric traces, corrosion resistance and prevention of direct light , Ensure stable performance for long-term use. The service life is the same as that of the cable body.
3M Cold shrinkable cable terminal, unique material formula and manufacturing process, make it closely adhere to the main insulation of the cable , Provide constant and good radial pressure to the cable body , The partial discharge is small, the initial voltage is high, the insulation impact level is higher than the existing standard level, and the waterproof and sealing performance is good , Same as cable body " breathing " 。
All products have passed the certification of the world's leading test institutions and the Electrical Equipment Quality Inspection Center of Wuhan High Voltage Research Institute of State Power Corporation of China.
four Complete quality control Product conforms to the United States IEEE-48 、 Germany VDE 0278 And China GB11033-89 And other international standards ISO9002 Certification of quality system standards. 3M The company has set up in the same industry in the United States, Germany and other places , Large scale R&D center , Provide technical development at any time , Detection and support , To ensure product quality.
