Product catalog summary

Specifications:
The silicone control and connection cable complies with DIN VDE 0250-1, DIN VDE 0285-525-2-83, and DIN EN 50525-2-83 standards. It operates within a temperature range of -25°C to +180°C when flexible and -60°C to +180°C when fixed. The permissible operating temperature of the conductor is +180°C. The nominal voltage is AC U0/U 300/500 V, with a test voltage of 2000 V and a breakdown voltage of 4000 V. The minimum bending radius is 7.5 times the outer diameter for flexible installations and 4 times for fixed installations.

Cable Structure:
The cable consists of finely stranded, tinned copper wire according to DIN VDE 0295 Class 5 / IEC 60228 Class 5. It features silicone core insulation and core identification according to DIN VDE 0293-308. For 2-5 cores, color coding is used, while 6-25 cores are black with consecutive white labeling. A protective conductor is included starting with 3 cores. The outer sheath is silicone, colored red-brown, with length markings in meters.

Properties:
The cable is resistant to ozone, oxygen, weathering, alcohols, dilute acids, alkalis, saline solutions, oxidizing agents, high molecular weight oils, vegetable and animal fats, plasticizers, clophen, and seawater. It is halogen-free, has a high flash point, and leaves an insulating SiO2 layer when exposed to flames. It maintains dielectric strength and insulation resistance even at higher temperatures.

Tests:
The cable is halogen-free according to DIN VDE 0482-754-1 / DIN EN 60754-1 / IEC 60754-1 and has low corrosiveness of combustion gases according to DIN VDE 0482-754-2 / DIN EN 60754-2 / IEC 60754-2. It is flame-retardant according to DIN VDE 0482-332-1-2 / DIN EN 60332-1-2 / IEC 60332-1-2 and has EAC certifications and approvals.

Application:
Silicone cables are designed for environments with extreme temperature changes. They are suitable for temperatures down to -60°C and are halogen-free, making them ideal for power stations. They are also used in steel production, aviation, shipbuilding, and ceramic, glass, and cement industries. The elastic core insulation makes them suitable as flexible connection cables.

Notes:
The conductor is constructed metrically (mm²), with AWG numbers provided for reference. For fixed installations, cables should be installed in open, ventilated systems to prevent mechanical property degradation at temperatures above 90°C.

The document includes a detailed table listing part numbers, core configurations, approximate AWG, outer diameter, copper weight, and total weight for various cable specifications.

APPLICATION n Silicone cables were evolved for use wherever insulation is subjected to extreme temperature changes. The good performance of the environmental resistant properties means that silicone cables can be used at temperatures down to -60°C. Silicone cables are halogen-free cables and are especially suited for installation in power stations. They have also found their uses in the steel producing industries, aviation industry, ship building as well as in ceramic, glass and cement factories. Due to elastical characteristic of core insulations, these are used as flexible connection cable NOTES n • the conductor is metrically (mm²) constructed, AWG numbers are approximated, and are for reference only • for fixed installation, always install in open, ventilated pipe or duct systems; otherwise, a combination of high temperatures above 90°C and the absence of air would affect the mechanical properties of silicone Cu-weight kg/km Weight kg/km, approx.
