1. Cold shrink cable end caps are made of silicone rubber, a material that is chosen because of its very good insulating and protective properties.
2. Power cable endings are insulated, sealed, and protected by specialized cable end caps designed for these purposes only. Therefore, the components are well protected against any outside damage.
3. The end cap shrinks only at low temperature and fully covers the cables, so there is no requirement to use any extra heating devices to finish the job during the installation phase.
In the field of on-site electric power construction, old-fashioned ways of sealing the cable ends at both extremities are generally based upon heating equipment or the use of dedicated devices. Usually, the work site can greatly influence the installation time—specially when it is a very small area, an area with risk of fire, or outdoor works—which is why it becomes tricky to reconcile the efficiency of construction with safety measures.
To counteract these problems, our cold shrink cable end caps come in a shape of silicone rubber that is pre-stretched. The elasticity of the material allows the installation without the necessity of open fire source or of complicated tools. These caps readily adjust to different cable endings, hence, make installation more comfortable, and help lower operational hazards while ensuring safe, durable insulation and sealing from the power cable surroundings.
Product Introduction:
A cold shrink cable cap is an excellent sealing product made of silicone rubber pre-expanded material with high performance.Benefit from fast installation made of the elastic recovery of the material, no heat source or special tools is needed.
The seal is suitable for sealing power cables at low and medium voltages and offers good waterproof protection against water, humidity, dust, mechanical damage etc.
It is very common to use a sealing cap for cable ends at storing, transporting, installation and operation stage in order to be a barrier against moisture and other contaminants and, therefore, guarantee the safety, longevity, and stability of cable operations.

Product Advantages:
1. Rapid installation without heat tools; enhanced on-site safety.
3M cold shrink end caps feature a pre-expanded design that allows you to install them quickly by removing the central core and the cap shrinks rapidly, thanks to its own elasticity, to give an extremely tight fit on the end of the cable. Getting rid of reliance on heating equipment is a big advantage since this makes the process much easier and less complicated.
2. Excellently sealing and protected; can withstand harsh and challenging outdoor environments.
Rubber cable ends that are normally used for insulation of the cable end, made of either high-grade EPDM or silicone rubber, both materials known for their great resistance to water, moisture, and environmental degradation. The use of this protective material does not only prevent moisture, but also blocks out dust, sea salt spray, and other contaminants getting into the wires thereby keeping the wires intact. On top of that, they highly resist UV rays, ozone, acids, and alkalis, which allow them to be used for a long time in the areas covered indoors, outdoors, as well as underground.
Conforming to the ASTM G21 standard, the product showed great resistance to mold as no mold growth was observed for twenty-eight days of contact period which in turn ensures the product's long-term reliability in humid and highly active biological environments.
3. Sustained elastic pressure ensures a stable, long-term seal.
Cold shrinkable end caps employ the continuous radial shrinking force of the rubber material to create a tight pressure against the cable surface. By doing that, they are able to effectively counter the effects of environmental stresses such as vibration as well as thermal expansion and contraction. The product is designed to have minimal water absorption even when subjected to harsh environments of high temperature and moisture.
After being immersed in 90°C water for 24 hours, the test sample only gained 1.3 % of its initial weight before being immersed - a clear indication of the product's excellent ability to resist moisture absorption. In stark contrast to traditional sealing systems, this item is capable of withstanding a range of factors without failing - for instance, loosening or cracking - which leads to seal failure in time. As such, the product will be a significant support of the cable protection at the end part for a much longer duration.
4. Excellent insulation properties; extends cable service life.
3m cold shrink end caps are made from an insulating elastomer material whose main electrical performance features provide excellent insulation. Furthermore, the material is wear and aging resistant. Besides, the raw material itself features a tensile strength of 9.8 MPa, an ultra-high elongation at break - 720%, and a tear strength of 27 kN/m. All these features guarantee that a cover stays in the original shape after and even during stretching (during installation), during the whole period of operation of the cable, and returns to its shape after being stretched, therefore it won't get mechanically damaged and will continue to deliver the same reliable and consistent levels of electrical protection for bare ends of cables.
5. Compatible with a wide range of cable specifications to meet diverse application needs.
Our cold shrink cable caps fulfill the sealing demands for both power and communication cables with different diameters. You can install our cold shrink cable caps with confidence that you will get a durable seal and be able to carry out the job without any time-consuming procedures or adjustments. In addition to these characteristics, our cold shrink cable caps are also ideal for different scenarios such as power distribution systems, industrial machinery, and telecommunications networks.
Product Applications:
1. Industrial manufacturing and automation equipment.
Cold shrink cable end caps are a protection solution used to prevent oils and dirt to enter in motor leads, control cables and the connection points of the equipments. Besides being a shield against any kind of fluid like oil and moisture and even dust that could cause damage in those parts, these cold shrink cable end caps are used in industrial manufacturing, electrical installation and automation systems in general.
2. Marine and offshore engineering.
Designed to offer outstanding waterproofing, moisture resistance and even corrosion resistance, rubber cable end caps are used to safeguard the cable terminations on ships and offshore platforms, enduring very tough conditions, such as seawater and salt spray.
3. Renewable energy facilities.
Following are some limits for investment in projects by outside power e.g., wind power, solar power, and hydro power. Cable termination protection covers resistance against sunlight, rain, abrupt temperature changes, and mechanical movement. All of these properties combined not only increase the life span of these products but equally their high-performance qualities make them the best options under extreme weather conditions that usually come hand in hand with electric power– related works.
4. Power and infrastructure construction.
Cold shrink cable end caps can be applied on power distribution boards, cable junction boxes, and outdoor electrical devices to offer enduring sealing as well as insulation protection to cable terminations.
