Silicone Elastomers for Infrastructure and Energy-Transmission and Distribution

Momentive’s silicone elastomers support the transmission and distribution industry with electrically insulating and conductive silicone rubbers.

• Cable Accessories

Silicone rubber is a preferred material for production of cable joints, cable terminations and switch gear connectors. Due to the excellent mechanical and dielectric properties in combination with easy and cost-efficient processing, Silopren™ LSR are outperforming other materials in design and production of medium and high-voltage cable accessories. Silopren Electro LSR are special formulations with high tracking and erosion resistance for the use of outdoor applications (terminations). Electrically conductive Silopren LSR, specially developed for combination with insulating Silopren and Silopren Electro LSR, allows electrical field control for push-on joints and cold shrink accessories.

• Insulators and Surge Arrestors

Silicones for outdoor insulators, like long rods, line posts, hollow core, or surge arrestors housings, are exposed to high electrical and environmental stress. Thanks to the hydrophobic surface, silicone composite insulators provide a high flashover resistance. Hydrophobicity and the dynamic properties like hydrophobicity recovery or transfer are key to providing the added value of enhanced pollution performance, no matter if the material is LSR or HCR.
