Silverline Metal Engineering Pvt. a premier manufacturer, supplier, exporter, trader of highly durableAngle Iron DSL System. We are based in Maharashtra, India where the system is manufactured by following industry standards and combining latest technology with skills. We have robust infrastructural unit, packaging and R&D unit to provide the best product.

Gravity Type current collector

1. Gravity type Current Collector:

Apart from using shrouded bus bar system Steel Industry in India still finds angle iron bus bar system preferable to use for EOT CRANES, TRANSFER CARS, and INGOT CARRIERS where in current collection is done by moving current collectors along stationary electric supply AC or DC. These are easy to install and can withstand harsh working conditions. Most end users prefer this because of its easy in house maintenance possibility.

With this perspective we have come out with manufacturing of all type of accessories required for these bus bar system. We supply ceramic insulators, munks as well as gravity type current collectors suitable for Angle Iron or Rail type Bus bar system. Our range varies from 150 to 1200amps. We supply shoes made of cast iron, cast steel, Brass, Bronze or phosphor bronze.

We can also manufacture and supply current collectors and accessories as per customers design and requirement.

2. Insulator:

We are the leading supplier of Insulators required to be used in angle iron DSL's.

We design and install angle iron DSL system up to 2000 amps. And we use hot moulded fiber reinforced polyester resin based insulator. We also use porcelain based Insulator.

Due to very high mechanical and electrical strength epoxy moulded insulators are extremely popular. Various sizes of insulators are manufactured and supplied by us.

We can also supply insulators used in wire rope trolley system.

3.Earth Current Collector:

Normally in mobile electrification system (RYBG) green stands for neutral and earth is normally neglected in the system for mobile equipments Silverline has designed earth current collector which can be easily attached to the equipment and can move along with crane or any other equipment to transfer eddy current to the rails and these rails can be firmly grounded to the earthing system.


It is a single pole DSL system. Copper strips of high conductivity are used as conductors for high performance. We recommend this for SME size factories installing smaller capacity cranes requiring not more than 140amps. This system is very easy to install and being joint less has less failure rate. Wear and tear is also less which improves life of current collectors' by atleast 50%. Smooth running of the DSL ensures best performance of control panels with VFD drives.


Features of Joint Less DSL System:

• Quick and easy installation
• No expansion problem
• Indoor and outdoor installation
• Tape form copper conductor

Application of Jointless DSL System :
