Description
Specifications
The Gap Jumper Lead is used to connect a supply to a stranded (Gapped) Train. This is where a train current collector shoe (pick up shoe) is no longer in connection with the power supply conductor rails.
Applications:
Gap Jumper Leads (GJ),
Approvals:
LU approved,
Key Features:
The cable connection is made directly to the top of the conduction plate.
- Positive Shoe 1 x 50mm2 Copper Cable
- Negative Shoe 1 x 50mm2 Copper Cable
- Material Micam EM42
- To assist with correct positioning the Gap Jumper Leads are colour coded Red for positive and Blue for negative.
- (This is an LUL colour requirement which could be tailored to suit other rail networks)
- The LCS Gap Jumper Lead design incorporates the following features:
- A shoe assembly that houses the conduction plate with integral magnets to suit various conductor rails, the cable connection point, cable restraint gland and conductor rail location guides.
- The conduction plate is made from plated Brass which is plated to provide good corrosion resistance.
- Connection force and stability assisted by the use of magnets. (Previously only the weight of the shoe with support of the cables by the operator)
- Magnets are located within the conduction plate to enable the magnetic field to interact with the conductor rail/s
- An insulated lifting handle is positioned towards the top of the connection shoe to allow easy positioning on the conductor rails.
- The supply cable enters the shoe assembly horizontally (previously the cable entered via the top of the shoe assembly, hence the need for support by the operator)
- The design allows the re-use of existing cables.
- The lift handle allows the removal of the shoe by tilting the assembly to disconnect the magnetic forces. Lift of force 16kgf.
- The rail guides also serve to provide a barrier by distance to the magnetic field.
- The Gap Jumper shoe fits all 4 of the Conductor Rail profiles used by London Underground including the composite Stainless Steel / Aluminium rail.
