Insulating bushing KB (TsP-142) — an element of railway fastenings used for electrical and mechanical insulation of metal fastening components. It provides reliable insulation of bolts and clips from the baseplate and rail, preventing short circuits in electrical circuits and corrosion of structural elements.

Description and application

Insulating bushings of the KB (TsP-142) type are manufactured in accordance with TU U 26.1-32693474-001:2006 from durable polymer materials — polyamide, nylon, or glass-fiber-reinforced composites. These materials feature high electrical insulation and mechanical strength and are resistant to temperature fluctuations, moisture, and ultraviolet radiation.

The bushings are used in elastic and clip-type rail fastening systems for R-50 and R-65 rails. They are installed in the holes of baseplates, providing insulation of bolted connections and overall structural stability.

Insulating bushing KB can be purchased in Ukraine from the company «Prombudkoliya». We offer a wide range of insulating and elastic elements for railway fastenings — bushings, pads, washers, clips, and baseplates.

Advantages of the insulating bushing KB (TsP-142):

High electrical insulation properties;
Protection of metal components against galvanic corrosion;
Strength and resistance to loads under track vibration;
Long service life and resistance to external climatic factors.
