A 110 punch block. A 110 block is a type of punch-down block used to terminate runs of on-premises wiring in a structured cabling system. The designation 110 is also used to describe a type of insulation displacement contact (IDC) connector used to terminate twisted pair cables, [1] which uses a punch-down tool similar to the type used for the older 66 block.
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 near the top just below the crown. The conductor passes through this groove and is tied to the insulator with annealed wire of the same material as the conductor. Pin ...
When the host conductor is a phase-wire, one of the conductors that carry the electric current in the electricity network, a phase-to-ground insulator is required at every location where the wrapped cable leaves the conductor. The phase-to-ground (PTG) insulator is a device that provides electrical isolation whilst allowing optical continuity ...
Victor Insulators, Inc. based in Victor, New York was founded in 1893 by Fred M. Locke, and is the oldest electrical insulator company in North America. They originally made glass insulators for electrical lines. They suspended operations during the Great Depression but resumed operations in 1935 as Victor Insulators. Among their product mix ...
Bulk insulators block conductive heat transfer and convective flow either into or out of a building. Air is a very poor conductor of heat and therefore makes a good insulator. Insulation to resist conductive heat transfer uses air spaces between fibers, inside foam or plastic bubbles and in building cavities like the attic.
Whitall Tatum entered the insulator manufacturing market in 1922, mass-producing them for use on power and communications lines across the country. Armstrong Cork Corporation purchased Whitall-Tatum in 1938, continuing insulator production under the Armstrong trademark. Production continued after a 1969 purchase by Kerr Glass Manufacturing ...
The International Association of Heat and Frost Insulators and Allied Workers (AWIU or Insulators) is a trade union in the United States and Canada, founded in 1903. It is affiliated with the AFL–CIO and the Canadian Labour Congress and the North America's Building Trades Unions .
G-10 or garolite is a high-pressure fiberglass laminate, a type of composite material. [1] It is created by stacking multiple layers of glass cloth, soaked in epoxy resin, then compressing the resulting material under heat until the epoxy cures. [2] [3] It is manufactured in flat sheets, most often a few millimeters thick.
