Nabla Spring Blade is a direct rail fastening system that offers enhanced performance for tracks with tight radius curves. It has been proven in installations for several decades and is recognised for its simple installation and maintenance. By maintaining the track gauge, it significantly increases the life expectancy of assembly components.
Technical Features
1.High clamping force An anchor screw is tightened to the contact, ensuring a consistent application of clamping force on the rail and a large range of torque. The high clamping force combined with the design of Nabla Rail Clip prevents rail roll.
2.Glass-reinforced material The glass-reinforced material used in the lateral insulators creates a high level of mechanical strength and good lateral force absorption.
3.Adjustable insulators A good level of lateral adjustment is provided via the insulators to deal with track gauge and alignment. This allows fine gauge tuning by 1.25mm increment, ±7.5mm per rail seat. 4.Electrical insulation Provides electrical insulation of over 10 K Ohms.
