Difference of Common Rail Joint and Insulated Rail Joint
Material Composition
Common Rail Joint: Typically made of steel.
Insulated Rail Joint: Utilizes insulated coating or a polyurethane plate to provide electrical insulation.
Electrical Conductivity
Common Rail Joint: Conducts electricity, as it is made of steel.
Insulated Rail Joint: Non-conductive and non-magnetic, offering electrical insulation.
Corrosion Resistance
Common Rail Joint: May be susceptible to corrosion depending on the type of steel and environmental conditions.
Insulated Rail Joint: Often designed with corrosion-resistant materials to enhance durability.
Connection Method
Common Rail Joint: Typically connected using rail bolts to join the ends of two rails directly.
Insulated Rail Joint: Requires an insulated coating or polyurethane plate to be placed between the rail track and the rail joint before being bolted with fish bolts.
