Unraveling the Importance of Spiral Earthing Cables
1. What Is a Spiral Earthing Cable?
Spiral Earthing Cable is a cable with the earthing wire made into a spiral shape.
These cables are usually 4mm2 6mm2 or so.
The spiral-type cable prevents the earth cable from falling off when someone moves the equipment.
2. Why Spiral Earthing Cables Matter
Spiral Earthing Cables are primarily designed to prevent static grounding and auxiliary electrical equipment enclosure grounding.
Grounding spiral cables can protect personal safety, and equipment safety, to avoid static electricity or spark-induced hazards.
✅ Anti-static Earthing
Anti-static grounding is the process of grounding oil and gas tanks, pipelines, trailers, and construction machinery. It also applies to refueling equipment, airport equipment, and other situations. This helps prevent static hazards.
✅ Auxiliary Equipment Enclosure Grounding
-Grounding between the vehicle carrier body and the main grounding wire system
-Extension of the protective grounding of the enclosure of portable removable equipment.
✅Why do I need a spiral earth cable?
In some mobile setups, trailer vehicle systems can have grounding cables that come loose or fall off. This can waste space badly. Spiral grounding cables save space and provide electrostatic safety for mobile installations.
3. Key Features & Technical Specifications
| Attribute | Details |
|---|---|
| Conductor | Pure copper / Tinned copper / Stainless steel |
| Cross-sectional Area | 4mm² 6mm² |
| Insulation Material | PUR (excellent oil, abrasion & chemical resistance) |
| Cable Colors | Yellow-green, green, blue |
| Temperature Range | -40°C to +80°C |
| Accessories | Aluminum clamps, stainless steel clamps, terminals |
| Certifications | ATEX approval (for explosive environments) |
As static spiral cable is commonly used in some commercial vehicle trailers, pipelines, petrochemical industry. So it is usually PUR insulation. This material provides excellent resistance to oil and abrasion as well as chemical resistance.
