SIHF Silicone Insulated Power Cable 3x1.5mm² 180°C

The SIHF silicone insulated power cable with a 3x1.5mm² cross-section is a high-performance electrical cable engineered for environments subject to extreme thermal stress. Designed to operate reliably at temperatures up to 180°C, this cable features a robust silicone rubber insulation and outer sheath that provide exceptional flexibility and heat resistance. Its hose-like construction and durable material composition make it a dependable solution for fixed installations where standard PVC cables would fail due to heat degradation.

Advantages

The primary advantage of this cable lies in its specialized silicone construction, which maintains its physical and electrical properties even under continuous high-temperature exposure. Unlike conventional insulation materials, silicone rubber does not become brittle when subjected to intense heat, ensuring long-term safety and performance. Furthermore, the cable offers excellent flexibility, allowing for easy routing in tight spaces or complex equipment layouts. Its resistance to thermal aging makes it a cost-effective choice for demanding industrial and domestic applications.

Suitable for

• Sauna installations and heating equipment
• High-temperature lighting fixtures
• Industrial ovens and furnaces
• Thermal processing machinery
• Electrical connections in proximity to heat sources

When it may not be suitable

This cable is not intended for applications requiring high mechanical abrasion resistance, as the silicone sheath is softer than standard rubber or plastic coverings. It should also not be used in environments where it will be exposed to aggressive chemicals or oils that are incompatible with silicone materials.

Key specifications

• Conductor cross-section: 1.5 mm²
• Number of conductors: 3
• Insulation and sheath material: Silicone rubber
• Maximum operating temperature: 180°C
• Cable shape: Hose
• Flammability class: Eca

How to use

The cable should be installed by a qualified professional in accordance with local electrical regulations. When stripping the silicone insulation, ensure that the copper conductors are not nicked or damaged. Due to the flexibility of the silicone material, the cable can be easily routed through conduits or cable trays, but it should be secured to prevent excessive mechanical strain on the connection points. Ensure that the bending radius is respected to maintain the integrity of the internal conductors.

What to consider before purchase

• Verify the current-carrying capacity requirements for your specific application
• Ensure the installation environment is free from sharp edges that could cut the silicone sheath
• Confirm that the total length required is covered by the package size
• Check compatibility with existing cable glands and connectors

Usage recommendations: Always ensure that the cable is protected from direct mechanical impact and that all connections are properly terminated to prevent overheating at the contact points. Regularly inspect the cable for signs of physical damage if it is located in an accessible area.
