Test Link Box

Products Description

Test link box is durable, weather-resistant materials, our test link boxes are suitable for outdoor and industrial environments. The box is equipped with terminals or links made from highly conductive materials like copper or brass to ensure minimal resistance and long-lasting performance. Ideal for use in power plants, substations, telecom towers, and commercial buildings, the Test Link Box helps maintain the reliability and safety of your grounding system.

Available Variants

1. Single Bus Bar

The Single Bus Bar Test Link Box is ideal for standard earthing setups and here are the features of this test link box:-

• Designed for simple earth pit isolation
• Suitable for residential, commercial, and mid-size industrial applications
• Compact build for fast installation and low maintenance

2. Double Bus Bar

The Double Bus Bar test link box variant offers enhanced load handling and redundancy.

• Dual-bar structure ensures improved reliability and flexibility
• Best suited for large industries, substations, data centres, and high-load lightning protection networks
• Provides superior safety during earth testing procedures

Key Features of Test Link Box:-

• Easy Earth Resistance Testing: Allows quick disconnection of the earthing electrode for periodic testing without dismantling the system.
• High Conductivity Terminals: Fitted with copper or brass links for excellent electrical conductivity and minimal resistance.
• Weather & Corrosion Resistant: Built with durable materials (like powder-coated metal or polycarbonate) to withstand harsh outdoor environments.
• Secure Lockable Design: Comes with a lockable cover to ensure safety, security, and prevent unauthorized access.
• Compact & Easy Installation: Lightweight, space-efficient design that can be mounted on walls or near the earthing pit.
• Compliance with Standards: Designed in accordance with industry norms for reliable performance in industrial and commercial earthing systems.
• Maintenance-Friendly: Provides an accessible point for inspection and maintenance, improving overall system reliability.

Why Is a Test Link Box Important?

Even the most well-designed LPS can degrade over time due to corrosion, soil conditions, weather exposure, and mechanical damage. Regular inspection and testing of the earthing resistance is necessary to ensure that the system is still functioning correctly. Here are the benefits of a test link box: 

1. Simplifies Testing: Allows quick disconnection between down conductor and earthing for separate resistance testing.
2. Enhances Safety: Provides a safe point to isolate the system during testing or maintenance.
3. Compliance: Necessary for inspections required by IS/IEC 62305, IS 3043, and other national/international standards.
4. Convenience: Offers easy access for electrical engineers or maintenance teams.
5. Protects Infrastructure: Helps in early identification of faults in grounding systems.
