Watteredge offers a wide variety of high current air cooled power cables ideal for many different industries and applications including resistance welding, resistance heating and bus bar systems.

Each cable and jumper is designed and built to perform with maximum efficiency and economy, providing longer cable life and greater flexibility over standard jumpers.

Our in-house engineering team can manufacture high current air cooled power cables and jumpers to customer specification or we can assist with custom design concepts and fabrication.

Air Cooled Cable Specifications

Watteredge air cooled cables are designated as type DJ (dry jumpers).

• Made from non-insulated copper wire ranging from 400 to 2000 MCM
• Cable end termination options:
• Crimped lugs, compression terminals
• Press welded compression terminals.

Air Cooled Cable Options:

Air Cooled Cable with Isolated Conductor
DJ-IC Air Cooled Jumper

Isolated Conductor type dry jumpers are identified by “IC,”

The Air Cooled Jumpers increase cable life by correcting the common causes of failure as indicated in the following:

• Eliminates frictional wear between adjacent ropes by the use of rubber tubing.
• Reduces frictional wear between strands of adjacent bunches within a rope by reducing “wear points” from 36 to 9 within the rope cross section.
• Reduces strand failure at rear of terminal, resulting from the added Stabilizer Flare.
• Increases flexibility and versatility because of an improved insulation method, not requiring the standard lapped hose cover.

Air Cooled Cable with Stabilizer Collar
DJ-SC Air Cooled Jumper

• Increases dry jumper life by reducing strand failure at the cable terminal; this is accomplished by a slight increase in the minimum flex radius which in turn reduces overstressing.

Extra Flexible Air Cooled Cable
DJ-XF – Extra Flexible Air Cooled Jumper

• The Extra Flexible type Dry Jumper increases cable life by the use of 36 AWG copper rope stranding and an extremely flexible protective cover specifically designed for this application.
• The combination of the strand and cover increases the flexibility of the DJ-XF to over double that of the standard dry jumper. (DJ)
• This increased flexibility makes it ideal for all robotic applications or where limited space makes installation of standard flexes a problem.
• The Extra Flexible Air Cooled Jumper is currently available in 1000 MCM and 1200 MCM.
• Terminal dimensions and ordering specifications are identical to the standard dry jumper (DJ).

Ideal for these Air Cooled Cable and Jumper Applications:

Watteredge Air Cooled Jumpers and Water Cooled Jumpers are required to electrically connect distant points which move in relation to each other and ideal for:

• Connecting moveable gun-arms of certain types of welding guns to power cables
• Multiple spot welding machines
• Electrolytic Processes
• Fuel Cells
• Furnaces, Induction Furnaces (Glass, Metal Melting)
• ISO-Phase
• Plasma Equipment
• Plating
• Resistance Welding
• Switchgear
• Telecommunication
• Transformer and Rectifiers
