Wooden Attachment CA-40mm – Heavy-Duty Round Conductor Holder for Kelvin Bridge Testing
The Wooden Attachment CA-40mm is a precision-designed accessory used for securely holding large-diameter round conductors during low-resistance measurement using a Kelvin Bridge. With a sturdy 1-meter wooden base, it provides the stability needed for accurate and repeatable electrical testing.
Specifically engineered to accommodate 36 mm and 40 mm diameter conductors, this attachment is also compatible with conductor sizes ranging from 38 mm to 42 mm, making it highly versatile for industrial applications. The option to customize hole diameters—within the allowable limit of 76 mm combined—ensures that the attachment can be tailored to meet specific cable testing requirements.
Equipped with heavy-duty brass clamps mounted at both ends, the CA-40mm ensures firm and reliable sample holding, minimizing measurement errors caused by poor contact or instability. Its rugged construction makes it ideal for cable manufacturers, electrical testing facilities, and laboratories performing precise conductor resistance testing.
This attachment is an essential accessory for achieving consistent, accurate, and professional-grade results when measuring large-size conductors using Kelvin Bridge setups.
