A three-phase insulator used on distribution lines, typically 13.8 kV phase to phase. The lines are held in a diamond pattern, multiple insulators used between poles. Insulators are characterized in several common classes: Pin insulator - The pin-type insulator is mounted on a pin affixed on the cross-arm of the pole. The insulator has a groove ...
Strain insulators on high-voltage power lines. A strain insulator is an electrical insulator that is designed to work in mechanical tension (strain), to withstand the pull of a suspended electrical wire or cable. They are used in overhead electrical wiring, to support radio antennas and overhead power lines. A strain insulator may be inserted ...
Insulating these pipes using pipe insulation reduces energy into unoccupied rooms and prevents condensation from occurring on cold and chilled pipework. Pipe insulation is also used on water supply pipework to help delay pipe freezing for an acceptable length of time. Mechanical insulation is commonly installed in industrial and commercial ...
An insulator of a telephone transmission line A pin insulator ceramic plate used for 20 KV lines. A pin insulator is a device that isolates a wire from a physical support such as a pin (a wooden or metal dowel of about 3 cm diameter with screw threads) on a telegraph or utility pole.
Medium-voltage power lines with ceramic insulators in California Modular suspension insulators are used for high-voltage lines. Insulators must support the conductors and withstand both the normal operating voltage and surges due to switching and lightning. Insulators are broadly classified as either pin-type, which support the conductor above ...
Thermal insulators are materials that inhibit the migration of heat. For electrical insulators, materials that inhibit the migration of electric current, ...
The electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by temperature and temperature rise. The electrical insulation system is sometimes referred to as insulation class or thermal classification.
Insulator (electricity), a substance that resists electricity Pin insulator, a device that isolates a wire from a physical support such as a pin on a utility pole; Strain insulator, a device that is designed to work in mechanical tension to withstand the pull of a suspended electrical wire or cable; Mott insulator, a type of electrical insulator
