Introduction
The
Twinco Impedance Bond is a rugged, high quality,
self-contained product, designed for electrified
territories that utilize standard insulated joint
isolation of signaling currents. It meets all
applicable AAR specifications. Hundreds of Style
ST-1 2500 AMP units have been in service with
the Long Island Railroad (LIRR) since 1992.
All components are contained in a low profile heavy duty cast iron housing, designed for mounting between the rails and across two adjacent ties. A heavy duty ramped, and diamond patterned slip resistant, removable cover is provided for ease of installation, inspection, and weather resistance. The bonds are filled with oil or petrolatum to provide moisture and corrosion protection and to aid in cooling of the bond. All hardware is either stainless steel or zinc plated for corrosion resistance.
Twinco offers a variety of impedance bonds to suit numerous applications. In addition, customized models can be developed for special situations. For over 35 years Twinco has been manufacturing solutions for the needs of many rail/ transit customers.
