Details

Cable Structure

• Copper wire tinned, finely stranded acc. to DIN VDE 0295 Class 5 / IEC 60228 Class 5
• Core insulation: silicone
• Core identification acc. to DIN VDE 0293-308 (2–5 cores: colour coded; 6–25 cores: black cores with consecutive labeling in white digits)
• Protective conductor: starting with 3 cores (G = with protective conductor GN-YE, in the outer layer; x = without protective conductor)
• Cores stranded in layers with optimal lay lengths
• Outer sheath: silicone
• Sheath colour: redbrown
• Length marking: in metres

Properties

• Resistant to: ozone, oxygen, weathering effects, alcohols, dilute acids, alkalis, saline solutions, oxidising agents, high molecular weight oils, vegetable and animal fats, plasticisers and clophen, seawater
• Halogen-free
• High flash point
• Leaves an insulating layer of SiO2 when exposed to flames
• No significant changes in dielectric strength and insulation resistance even at higher temperatures

Tests

• Halogen-free acc. to DIN VDE 0482-754-1 / DIN EN 60754-1 / IEC 60754-1
• Corrosiveness of combustion gases acc. to DIN VDE 0482-754-2 / DIN EN 60754-2 / IEC 60754-2
• Flame-retardant acc. to DIN VDE 0482-332-1-2 / DIN EN 60332-1-2 / IEC 60332-1-2
• Certifications and approvals: EAC

Notes

• 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

Application

Silicone cables were evolved for use wherever insulation is subjected to extreme temperature changes. The good environmental resistance means that silicone cables can be used at temperatures down to -60°C. They are halogen-free and especially suited for installation in power stations, and are also used in steel producing industries, aviation, ship building, and in ceramic, glass and cement factories. Due to the elastical characteristic of core insulations, these are used as flexible connection cable.
