Cable holding device with electrical elevation system
Schütz Meßtechnik GmbH, Germany, provides the cable industry with high precision holding devices such as the model MAT 2000T which can be used to determine the electrical cable resistance of high and mid-range power cables. Using a 4-pole measuring technique according to Kelvin, all feed line resistances are eliminated. The measuring current is established via pneumatically operated chuck jaws while the measuring voltage is picked-up via spring-supported taps.
The current jaws, and thus the current feeding points, are arranged at a sufficient distance to the taps in accordance to DIN/IEC to ensure a constant and uniform distribution of the current across the measuring distance. The MAT 2000T is capable of measuring cables during manufacturing process by directly connecting the device to the cable where it is reeled up. Furthermore, the holding device can swing vertically to support different cable angles. After closing the safety covers, the pneumatic chuck jaws are activated and the measurement can start, using the company's built-in Microohmmeter MR 302 C-A. The MAT 2000T features a built-in IR-temperature probe which determines the cable temperature during measurement. The Microohmmeter MR 302 C-A then recalculates the measuring result back to 20°C. Three chuck jaws are used to maintain a tight fit and a stable contact during the measurement. A calibrated massive Cu testrod with known TK can be used to control the measuring resolution, including the temperature measurement.
