Diagonal cutting pliers (side cutters) Made with the jaws set at an angle and available in sizes from 100mm to 200mm. 1  Cutting conductors in confined spaces or close to electrical terminals.  Stripping the outer sheath of flexible cable ready for terminating.
By Anne Marie Helmenstine, Ph.D. A material that readily transmits energy is a conductor, while one that resist energy transfer is called an insulator. There are different types of conductors and insulators because there are different forms of energy. Materials that conduct electrons, protons, or ions are electrical conductors. They conduct electricity. Usually, electrical conductors have loosely bound electrons. Materials that conduct heat are thermal conductors. Substances that transfer sound are acoustical conductors. There are corresponding insulators for each type of conductor.
A semiconductor material has an electrical conductivity value falling between that of a conductor, such as copper, and an insulator, such as glass.n (intrinsic) semiconductor has a band gap that is smaller than that of an insulator and at room temperature significant numbers of electrons can be excited to cross the band gap. A pure semiconductor, however, is not very useful, as it is neither a very good insulator nor a very good conductor.
