Silicone cable, high temperature resistant acc. to UL/CSA SiHF UL/CSA 5G2.5mm² black, conductor identification acc. to DIN VDE 0293-308 23256

High-temperature silicone cable – reliability in extreme conditions

This 5-core silicone cable, with a cross-section of 2.5 mm², is designed to operate in demanding environments where standard cabling fails. It is characterized by exceptional resistance to high and low temperatures, making it an ideal choice for industrial and specialized applications. The cable meets UL/CSA standards, guaranteeing safety and compliance with stringent regulations.

Construction and properties

The cable is made of multi-strand copper conductors (class 5), covered with silicone insulation. The outer jacket is also made of silicone, providing additional protection against external factors. The cores are longitudinally twisted, and the protective conductor (yellow-green) is present from 3 cores and above. Core marking is done according to DIN VDE 0293-308 – black or colored cores with white numbering, which facilitates identification during installation and maintenance. The cable is halogen-free, increasing safety in the event of a fire – during combustion, a SiO2 coating is formed instead of toxic gases.

Applications and benefits

The cable finds application in a wide range of industries, including:

• Power plants: thanks to its resistance to high temperatures and dielectric properties.
• Steel, aerospace and shipbuilding industries: where flexibility and reliability in harsh conditions are required.
• Ceramics, glass and cement plants: resistance to abrasion and chemical substances.
• As a flexible connection cable: thanks to the high flexibility of the silicone insulation.

Additional advantages:

• Wide operating temperature range: from -60°C to +180°C (short-term up to +220°C).
• Chemical resistance: to oils, greases, alcohols, acids, alkalis and atmospheric conditions.
• High radiation resistance: up to 20x106 cJ/kg (up to 20 Mrad).
• Low bending radius: facilitates installation in tight spaces (flexible 7.5xØ cable, stationary 4xØ cable).
• Compliance with standards: UL Style 4476, CSA AWM II A/B and DIN VDE 0482-332-1-2 / DIN EN 60332-1-2 / IEC 60332-1 (equivalent to DIN VDE 0472 part 804 test method B), CSA FT1.

The core cross-section is 2.5 mm², and the outer diameter is approximately 12.4 mm. The rated voltage U is 500 V. The cable is designed to operate at a working voltage of 300/500V (VDE) or 600V (UL/CSA).
