Helukabel 23002 3-Core Silicone Cable 300/500V

The Helukabel 23002 is a high-quality 3-core silicone cable engineered for demanding environments where thermal stability and flexibility are critical. Rated for 300/500V, this cable features tinned copper conductors and a robust silicone insulation and sheath, ensuring reliable electrical performance in extreme temperature conditions ranging from very low temperatures up to high heat. Its halogen-free construction and resistance to various environmental factors make it a versatile solution for industrial and specialized applications.

Advantages

This cable offers exceptional resistance to ozone, oxygen, weathering, and various chemical substances, including alcohols, dilute acids, and oils. The silicone material maintains its dielectric strength and insulation resistance even under significant thermal stress. Furthermore, the cable is flame-retardant and, in the event of fire, leaves behind an insulating layer of SiO2, which helps maintain circuit integrity. Its high flexibility allows for easy installation in complex machinery and tight spaces, while the tinned wire construction provides enhanced protection against corrosion.

Suitable for

• Industrial heating systems and furnaces
• Lighting installations in high-temperature environments
• Power stations and energy distribution
• Steel, glass, ceramic, and cement production facilities
• Aviation and shipbuilding industries
• Flexible connections for equipment exposed to extreme temperature fluctuations

When it may not be suitable

This cable is not intended for direct burial or installation in non-ventilated, closed systems where temperatures exceed 90°C, as the lack of air circulation can negatively impact the mechanical properties of the silicone insulation. It should also not be used in applications requiring high mechanical abrasion resistance, as silicone is softer than standard PVC or PUR jacketing.

• Halogen-free: Yes, compliant with IEC 60754-1
• Chemical resistance: Resistant to alcohols, dilute acids, alkalis, and various fats

How to use

When installing the Helukabel 23002, ensure that the cable is routed through open, ventilated pipe or duct systems if the operating environment consistently exceeds 90°C. This ventilation is necessary to preserve the mechanical integrity of the silicone sheath. The cable is designed for flexible use, but care should be taken to avoid sharp bends or mechanical pinching during installation. Connections should be made by qualified personnel following standard electrical wiring practices for the specific equipment being powered.

What to consider before purchase

• Verify the required cross-section for your specific current load requirements.
• Ensure the installation environment allows for adequate ventilation if high temperatures are expected.
• Check that the chemical exposure in your facility is compatible with silicone-based insulation.
• Confirm the length required for your project as the cable is supplied in meter increments.

Usage recommendations: For optimal longevity, always install this cable in well-ventilated areas when operating at high temperatures. Avoid mechanical stress or abrasion that could compromise the silicone outer sheath.
