Description
WIN INDIA Copper Test Bond Heavy-Duty Brass Grounding Disconnecting Clamp (Round & Square / I-TB-CU & I-TB-SQ) Excellent for Earthing Cable Connector & Exceptional Reliability
The INDIA Copper Test Bond series delivers a high-conductivity electrical testing and disconnecting clamp designed specifically for copper lightning protection systems and structural earthing networks.
Positioned along down-conductor lines, a test bond serves as a critical removable link.
It allows maintenance teams, site inspectors, and electrical testing engineers to safely disconnect the roof air termination network from the ground electrode system to measure individual earth resistance without interference from stray electrical currents.
Manufactured from high-grade copper alloy (brass), the INDIA Copper Test Bond line provides outstanding electrical conductivity, high mechanical strength, and superior resistance to corrosion when installed outdoors or in damp environments.
This ensures minimal signal loss and low contact resistance across lightning down-conductors over long operational lifespans.
Key structural and functional advantages of the INDIA Copper Test Bond series include:
-
Essential Isolation for Testing: Enables quick temporary disconnection of conductor lines for annual earth pit resistance measurements and electrical continuity testing.
-
High-Conductivity Brass Body: Premium copper alloy construction provides reliable current flow during lightning discharge events and prevents oxidation breakdown.
-
Heavy-Duty Threaded Fasteners: Engineered with robust bolts and corner screws that clamp copper conductor tapes or round wires tightly to avoid loosening under mechanical vibration or thermal expansion.
-
Versatile Form Factors: Available in two distinct geometric options to match layout requirements and mounting aesthetics: Round Type (Order Code: I-TB-CU) and Square Type (Order Code: I-TB-SQ).
Whether mounted on commercial building facades, substation structures, or industrial plant earthing networks, the INDIA Copper Test Bond series ensures dependable test access and durable conductor clamping.

Frequently Asked Questions (FAQ)
Q1: What is the primary function of an INDIA Copper Test Bond?
A : An INDIA Copper Test Bond acts as a removable electrical link in a lightning protection down-conductor network.
It allows technicians to isolate the earth pit system from the main roof structure to perform accurate earth ground resistance measurements.
Q2: What is the difference between I-TB-CU and I-TB-SQ?
Both models serve the same electrical disconnecting purpose but differ in design and form factor:
-
I-TB-CU (Round): Features a circular brass base with heavy central and peripheral clamping studs.
-
I-TB-SQ (Square): Features a square flat plate design secured with four corner clamping screws, suitable for copper tapes.
Q3: Why should I choose a copper/brass test bond over an aluminium test bond?
A : Copper/brass test bonds are designed specifically for copper conductor networks (such as bare copper tape or stranded copper cable).
Matching copper fittings prevents galvanic corrosion caused by joining dissimilar metals.
Q4: How is an earth resistance test performed using this clamp?
A : During periodic inspection, the technician loosens the clamping bolts/screws to separate the upper down-conductor from the lower earth connection.
An earth resistance meter probe is attached to the ground-side fitting to take accurate readings before the clamp is re-tightened.
Q5: Are these copper test bonds weather-resistant for outdoor wall installations?
A : Yes, the copper alloy (brass) construction offers high durability and natural resistance to corrosion, making it well-suited for exposed exterior building walls and harsh environmental conditions
