Silicone Rubber Wire is a flexible single-core electrical wire designed for internal equipment wiring and electrical connections requiring reliable insulation, excellent flexibility, and long-term stability. Manufactured with stranded tinned copper conductors and silicone rubber insulation, it is widely used in industrial equipment, household appliances, control systems, heating devices, and electrical installations operating under demanding conditions.

Designed for Reliable Equipment Connections

Built for Compact Equipment Layouts
The flexible stranded copper conductor allows easier routing through terminals, cable ducts, and confined installation spaces, making installation more efficient in electrical cabinets and compact equipment.

Maintains Stable Electrical Performance
Silicone rubber insulation provides consistent dielectric performance during continuous operation, helping maintain reliable electrical connections under changing environmental conditions.

Supports Long-Term Equipment Reliability
The combination of flexible conductors and durable insulation reduces mechanical stress caused by bending, vibration, and repeated movement, contributing to longer service life.

Q: What temperature range can the wire withstand?

A: The wire is designed for continuous operation from -60°C to +180°C, depending on the specific construction and application requirements.

Q: Which conductor sizes are available?

A: Standard conductor sizes range from 0.5 mm² to 10 mm², with additional sizes available for customized production.

Q: Can tinned copper conductors be supplied?

A: Yes. Tinned copper conductors are available to improve corrosion resistance and long-term reliability, especially in humid or demanding environments.

Q: Can the wire be customized?

A: Yes. We can customize conductor size, insulation color, voltage rating, wire marking, packaging, and other specifications according to project requirements.

Q: How do I choose the right Silicone Rubber Wire?

A: The selection depends on operating temperature, current capacity, installation environment, conductor size, and application. Our technical team can recommend a suitable specification based on your project.

Q: Which standards does the wire comply with?

A: The wire can be manufactured in accordance with IEC 60245, GB/T 5013, UL 3135, and other applicable standards depending on customer requirements.

Q: What are your MOQ and lead time?

A: The MOQ is generally 500–1000 meters per specification, while standard products are usually delivered within 7–15 working days. Customized orders may require additional production time.

Q: How should Silicone Rubber Wire be stored?

A: The wire should be stored in a clean, dry environment away from direct sunlight, corrosive chemicals, and excessive mechanical pressure. Proper storage helps maintain insulation performance and extends service life.
