Key Applications
Insulator Components
Custom-engineered rubber components for composite and polymer insulators that provide exceptional electrical insulation properties, UV resistance, and hydrophobicity. Our materials maintain integrity in high-voltage environments while resisting tracking, erosion, and environmental degradation.
Bushing & Termination Seals
High-performance sealing systems for transformer bushings, cable terminations, and switchgear connections designed to prevent moisture ingress and maintain dielectric integrity in critical high-voltage equipment.
Transformer Components
Specialized rubber gaskets, seals, and expansion membranes for power transformers that accommodate thermal cycling while maintaining oil containment and environmental protection throughout decades of service.


Vibration Dampening Systems
Custom-formulated rubber components for transmission line dampers and substation equipment isolation that reduce mechanical vibration, minimize corona effects, and extend infrastructure lifespan.
Line Hardware Protection
Weather-resistant rubber components that enhance the durability and performance of transmission line hardware, providing shielding from environmental factors and electrical stress.
Switchgear & Cabinet Seals
Environmental sealing systems for pad-mounted switchgear, junction boxes, and control cabinets that prevent moisture ingress, resist UV degradation, and maintain performance across extreme temperature ranges.
Underground Distribution Components
Custom rubber components for underground cable accessories including elastomeric separable connectors, load-break elbows, and cable junction points engineered for decades of submersed service.
Smart Grid Equipment Seals
Precision-molded seals and gaskets for smart metering infrastructure, sensors, and communication equipment that provide long-term protection in outdoor environments.
Arrester & Cutout Components
Elastomeric components for surge arresters, fuse cutouts, and protective devices that maintain electrical isolation while withstanding environmental extremes and electrical stress.
Secondary Network Components
Custom rubber components for network protectors, submersible equipment, and vault applications that maintain performance integrity in challenging urban environments.
