Product Overview
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. Suitable for all track types, including heavy haul, Nabla Spring Blade offers improved electrical insulation and lateral force absorption. The unique use of glass-reinforced material in the lateral insulator also offers increased mechanical strength.
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.
Product Advantages
1. As a result of its deep post insulator, Nabla Rail Clip offers exceptional resistance to wear caused by lateral loads. This reduces track maintenance overheads.
2. Nabla Rail Clip is simple to install, saving time and money.
3. The use of glass-reinforced material results in a high level of mechanical strength and good lateral force absorption.
4. Nabla Rail Clip offers higher electrical insulation than similar systems, making it an efficient, effective option.
5. The system has been adapted for compatibility with all types of rail, including grooved, AREMA and industrial. The system offers a good level of lateral adjustment via the insulators, allowing fine gauge tuning and alignment.
6. By maintaining the track gauge on tight radius curves, Nabla Rail Clip increases the life expectancy of assembly components.
