For multi- and fine-stranded conductors, solder two-layer insulation with thermoplastic inner adhesive, after shrinking a watertight connection is created, shrinking temperature: 130°C, temperature range: -55°C to +125°C, volume resistance (ohm cm): greater than or equal to 10 to the power of 15, dielectric strength (KV/mm): greater than or equal to 25, dielectric strength> 600V, max.: 12V,
