In the construction and operation maintenance of power transmission networks, the insulation performance and durability of cable accessories directly determine the operational safety and service life of the power system. As a core insulating material supporting medium and low, medium and high voltage cables, double 2,5 silicone rubber has become a mainstream material for the production of key accessories such as cold-shrink terminals and sheaths of power cables, and is widely used in various power engineering construction scenarios.



In accordance with industrial material standards, this special silicone rubber for cable accessories adopts a hardness range of 60-70 Shore A, which fits the molding process requirements of most cable accessories. Compared with ordinary rubber materials, it features excellent fluidity and is suitable for industrial production processes including high-pressure injection molding, compression molding and extrusion molding. It meets the needs of large-scale and standardized mass production, effectively improving the production efficiency and finished product qualification rate of cable accessories.

In terms of performance, the silicone rubber has stable electrical insulation performance with low loss, providing reliable long-term insulation protection for cable lines and avoiding potential safety hazards such as electric leakage and breakdown. Meanwhile, it possesses outstanding weather resistance, aging resistance and pollution resistance. It can adapt to harsh outdoor working environments with intense sunlight, temperature changes, humidity and dust, resisting cracking and aging during long-term service and reducing replacement and maintenance costs.

At present, double 2,5 silicone rubber is widely applied in medium and low voltage cable accessories, mainly used for manufacturing cold-shrink terminals and cable sheaths. It solves the industry pain points of traditional insulating materials such as easy aging, difficult molding and poor outdoor adaptability.

With the continuous upgrading of power grid infrastructure, outdoor power equipment has higher requirements for the durability, stability and process adaptability of insulating materials. As an important type of new power material, high-performance special silicone rubber for cables will continue to be optimized, providing solid material support for the safe and stable operation of power grids and helping the high-quality and sustainable development of power infrastructure.
