Single-core silicone wire, high temperature resistant SiF 1x4mm² red 23802

High-temperature silicone wire – reliability in extreme conditions

This single-core silicone wire is designed to operate in demanding conditions where standard cabling fails. It is characterized by exceptional resistance to high and low temperatures, making it an ideal choice for industrial applications, as well as in installations requiring flexibility and safety. This wire is particularly valued for its halogen-free construction, which increases fire safety.

Construction and properties

The wire is made of multi-strand copper core, providing good flexibility and ease of installation. The core is insulated with high-quality silicone, which guarantees temperature resistance in the range of -60°C to +180°C in stationary operation and from -25°C to +180°C in flexible operation. Additionally, the silicone insulation provides resistance to many chemical substances, such as oils, greases, solvents, and acids and alkalis. The outer diameter of the wire is 4.4 mm, providing convenience in routing and connection. The rated voltage U0/U is 300/500 V.

Applications and benefits

SiF 1x4mm² red wire finds wide application in many industries:

• Metallurgical and steel industry: Due to its resistance to high temperatures.
• Aerospace industry: Where lightness and reliability are required.
• Cement and ceramic industry: In environments with high temperature and dust.
• Power plants: Halogen-free construction increases fire safety.
• Heating devices: Ideal for connecting heating elements.
• Industrial lighting: Provides safe power supply to lighting fixtures in difficult conditions.

Thanks to its flexibility, this wire facilitates installation even in tight spaces. Halogen-free construction minimizes the risk of toxic gas formation during a fire, which translates to greater safety for people and property. In addition, high chemical resistance ensures long-term reliability in aggressive industrial environments. The wire meets the requirements of IEC 60332-1-2 standard regarding flammability and PN-EN 60754-1/2 standard regarding halogen-free construction.
