Insulated rail joint overview
The insulated rail joint is a special type of rail connection used to join two railway tracks, also known as a railway fishplate. Unlike other types of rail joints, insulated rail joints are made of insulating materials, specifically high-strength composite materials. In comparison to common rail joints, insulated rail joints can isolate electric current and protect against lightning strikes. Due to their wide applications, various sections of railway tracks increasingly demand insulated rail joints, particularly in situations where electrical resistance is needed.
Insulated rail joint application
Insulated rail joint for light rail 8kg, 9kg, 12kg, 15kg, 18kg, 22kg, 24kg and 30kg
Insulated rail joint for heavy rail 38kg, 43kg, 50kg and 60kg
Insulated rail joint for crane rail QU70, QU80, QU100 and QU120
Insulated rail joint advantages
Insulated rail joint GNEE manufactured offer many advantages such as corrosion resistance, rust prevention, UV protection, insulation, non-conductivity, and non-magnetism. Conforms to the irregular shapes of the track. The insulated rail joint plays a pivotal role in ensuring the efficiency and longevity of railway systems.
Insulated rail joint types
GNEE manufacture and market various following types of insulated joints with different properties based on the type of force application, installation, and manufacturing. And we can customize all kinds of insulated rail joint based on your needs.
● Bonded insulated rail joint
The bonded insulated rail joint is a connector used in railway systems with long welded rails.
It secures insulation material through bonding or welding. Its purpose is to achieve both electrical isolation and the transmission of longitudinal forces in the track.
● Polyurethane insulated rail joint
Polyurethane insulated rail joint is a railway connector that involves bonding polyurethane insulation to micro-alloy joint bar sections. This polyurethane plate is designed to offer reliable circuit isolation and maintain electrical stability in heavy rails under varying environmental conditions.
