Approvals

Cable Construction

Type SiF

Tinned copper conductors
≥0.5 mm² to DIN VDE 0295 cl. 5, BS 6360 cl. 5 and IEC 60228 cl. 5
for 0.25 mm² = 14x0.15 mm
Silicone conductor insulation

Type SiFF

as SiF but with high flexible copper strands (see technical information)
Strand make-up
0.25 to 1.0 mm² - cl. 6 col. 7
(single wire Ø 0.05 mm)
1.5 to 10 mm² - cl. 6 col. 6
(single wire Ø 0.07 mm)

Application

Special cables for use in high or low temperature areas. They are used mainly in the steel producing industries, in aviation industries as well as in ship building, cement, glass and ceramic factories, especially suited for use in power stations (halogen-free).

= The product is conformed with the EC Low-Voltage Directive 73/23/EEC and 93/68/EEC.

Properties

Advantages: High ignition or flash point
Resistant to high molecular oils, fats from vegetables and animals, alcohols, plasticizers and clophenes, diluted acids, lye and salt dissolution, oxidation substances, tropical influences and weather, lake water, oxygen
Halogen-free according to DIN VDE 0482 part 267 / DIN EN 50267-2-2 / IEC 60754-2 (equivalent DIN VDE 0472 part 813)
Behavior in fire no flame propagation test according to DIN VDE 0482-332-1-2 / DIN EN 60332-1-2 / IEC 60332-1 (equivalent DIN VDE 0472 part 804 test method B)
For laying as a fixed installation only in open or ventilated pipe systems as well as in ducts. Otherwise the mechanical properties of the silicon are reduced by the enclosed air at temperatures exceeding +90°C/+194°F.
