Cables used for connecting a Pt100 sensor usually have copper-based conductors. In our own sensors we use plated copper either tin silver or nickel-plated depending on the temperature range required. It is however permissible to use plain copper. For very high temperatures we use Nickel-based cables.

· When a shear stress is applied to an object the force trues to cut or slice through like a knife cutting through butter. A clevis bolt which is often used to secure a cable to a part of the airframe has shear stress acting on it. As shown in Figure 5 a fork fitting is secured to the end of the cable and the fork attaches to an eye on the airframe with the clevis bolt.

· · Copper Wire/Cable Granulator and Separator (also named waste wire/cable recycling machine) is the machine used to crush waste copper wire/cable and separate copper and plastic which is an environment-friendly equipment.
· When first introduced approximately 40 years ago underground locators needed to do little more than find buried water gas or sewer lines. Today locating has become more complex as telecommunications cables join utility lines in the underground environment. Surprisingly though today`s underground cable locators rely on the same basic technology found in their early counterparts-

Pre-Loaded Copper Patch Panels save design and installation time with fully assembled components Hybrid Cable Take advantage of DC power and fiber in one cable
· The working of the inverter generator ensures the constant frequency. The engine runs the alternator to generate the AC electricity which is converted to DC and then again AC.The whole process is controlled with the help of a microprocessor.. When the load is less the microcontroller will reduce the speed of the engine and so the noise is also reduced while the frequency remains the same.
· This mineral insulated cable production process principle is that the copper belt and copper rod can be infinitely welded and let the copper belt longitudinal welding moulding wrapped around the copper rod. In the copper rod and welding between the copper belt filled with magnesium oxide powder.
