EV Cable Insulation and Connectors

Provide high-voltage insulation for electric-vehicle cables, wiring harnesses and connectors.

Design with confidence. Meet your needs for high-voltage insulation in hybrid- and electric-vehicle cables, wiring harnesses and connectors. Try Silastic® brand silicone elastomers and Dow Corning® brand silicone rubber to help you achieve system reliability and durability without special heat shields or added environmental protection.

Maintain dielectric integrity with proven silicone elastomers
With Silastic and Dow Corning silicone rubber elastomers, you can meet performance specifications for high-strength insulation on charging cables, wiring harnesses and high-voltage connectors for hybrid and electric vehicles. These elastomers offer you:

• Excellent dielectric properties to handle high system voltage and current
• Reliable insulation strength over a wider temperature range than many organic elastomers can handle, from -40 to 200°C (-40 to 392°F)
• Long-term flexibility without becoming brittle, checking or cracking due to age, exposure to ultraviolet (UV) rays or weathering
• High resistance to tracking when exposed to moisture, salt spray, ozone and environmental contaminants
• Durable resistance to abrasion and wear even when exposed to vibration, tight clearances, complex routing and repeated handling

Extend your options for high-performance hybrid- and electric-vehicle insulation
Meet requirements for cable and wiring harness insulation and high-voltage connector designs. Gain added productivity and performance with:

• Liquid silicone rubber (LSR)  (PDF) elastomers for high-speed cable and wire processing
• Fluorosilicone rubber (FSR)  (PDF) elastomers for resistance to fuels, oils and solvents
• Fluoro liquid silicone rubber (F-LSR)  (PDF) for fuel resistance with liquid process speeds
• Custom compounds can be developed to meet your system design specifications and performance requirements
• Application expertise and consulting services for customized wiring harness, cable insulation and high-voltage connector development
