DQ-630 Type Four Terminal Wiring Clamp
DQ-630 Type FourTerminal Wiring Clamp
DQ-630 type universal conductor resistance clamp is the auxiliary equipment for measuring the DC resistance of wire and cable conductors, which can be used together with QJ36, QJ57, SB2230, PC36C and other double bridge and digital bridges to measure conductor resistance. It meets the standard requirements given in GB/T3048 Test Method for Electrical Performance. The baseplate is made of aluminum alloy section, and is provided with independent clamping head on current end and voltage test end. The current-end clamping end may be used to adjust the distance with the test end (voltage clamping head) according to the sectional area of the conductor measured. In addition, its performance indicators and technical parameters comply with the requirements of relevant national standards.
Current-end shape: Right-angle jaw shape
Voltage-end shape: Right-angle knife shape
Contact width of clamp：45mm
Space between current and voltage ends: Adjustable range
Length ofmeasurementwire：1000mm
Maximum cross section of the sample：630 mm²
