Product Description
Durable Grounding Lead for Temporary Grounding of Overhead Lines and Substation Equipment
A Grounding Lead, also commonly referred to as a grounding jumper or portable ground, is a fundamental and absolutely critical safety device in electrical power systems. It is a specially constructed cable assembly designed to create a deliberate, low-impedance connection between an isolated or de-energized electrical conductor and a verified ground point, such as the system ground grid or a grounded structure.

Key Features and Applications
- Creates a Safe, Zero-Potential Work Zone: Protects personnel by ensuring de-energized equipment remains at zero electrical potential, even if accidentally re-energized.
- Low-Impedance Path for Fault Currents: Provides engineered path for fault and induced currents using high-purity stranded copper construction.
- Essential for Lock Out Tag Out Ground Procedures: Critical final step in safety procedures for de-energized electrical work.
- Temporary Grounding for Maintenance: Used in substations and overhead lines during switching operations and maintenance activities.
- Equipotential Bonding: Eliminates step and touch potential risks by bonding metallic structures to equal electrical potential.
- Durable Field Construction: Built with flexible, fine-stranded copper and weather-resistant, high-visibility jackets for harsh environments.
- Multiple Configurations Available: Available in various lengths and setups including single leads and three-phase plus neutral kits.
- Personal Protective Grounding Systems: Central component of comprehensive electrical safety systems rated for specific fault currents.
- Rigorous Testing Requirements: Subject to regular visual inspections and high-current testing to ensure operational integrity.
- Safety Compliance Investment: Meets OSHA, NFPA 70E and other regulatory requirements for electrical safety programs.
The Grounding Lead is much more than just a cable; it is a purpose-built safety lifeline. It is the engineered solution that actively creates a safe working environment in the inherently dangerous field of electrical power. By providing a controlled, low-resistance path to ground, it ensures that unexpected electrical energy is safely diverted, protecting the lives of skilled professionals who build, maintain, and repair electrical infrastructure.
