Eaton COOPER POWER SERIES DirectConnect elbow arrester

Look to Eaton’s Cooper PowerE series 600 A 35 kV class DirectConnect

elbow arrester to offer wind farm customers significant cost savings and

ease of installation.

This new deadbreak design replaces three components:

bushing extender, loadbreak reducing tap plug and the traditional 200 A

elbow arrester. The DirectConnect elbow arrester is available in two design

options: VariGAP and M.O.V.E. Eaton values your trust in our experience to

engineer products that save you money.

Reliability, cost savings and ease of installation

Eaton is now combining their 40+ year track record in separable connectors

and 27 years in underground arresters to introduce the 600 A DirectConnect

elbow arrester.

Eaton offers a cost-effective design with a shorter stacking height.

With this design, you no longer have to worry about clutter or not being able to

fit your cable accessories into smaller enclosures. The DirectConnect elbow arrester

replaces three components with one and is over 50% smaller in size than the

traditional offering, cutting installation time by 80%.

Not only does this design save you money on direct material costs, but it also

reduces overall labor expenses.

The DirectConnect elbow arrester utilizes the design expertise and manufacturing

know-how that contractors, developers and owners alike have come to rely on from

Eaton. Specific for 35 kV wind farm applications, the VariGAP design option provides

enhanced temporary overvoltage (TOV) characteristics for superior MCOV performance

over time. The VariGAP design is available in 27 kV and the standard M.O.V.E. design

is available in 27 kV and 30 kV ratings. Installation is easy. Simply thread the adapter

into a standard 600 A bushing and install the DirectConnect elbow arrester onto the

bushing. The probe inside the arrester latches into the adapter.

Design features and benefits

• Save material costs with the DirectConnect arrester over bushing extender,

loadbreak reducing tap plug, and 200 A elbow arrester

• Reduce stocking requirements

• Shorter stacking height

• Decrease stacking height more than 50%

• Fits into smaller enclosures

• Reduces pulling force due to elimination of cantilever effect

• Easily retrofittable to existing 600 A installations

• Simply replace the bushing extender, loadbreak reducing tap plug and 200 A elbow

arrester with an adapter and a DirectConnect elbow arrester

• TOV performance

• Enhanced temporary overvoltage characteristics

• 36 kV—highest TOV in the industry

• Arresters that will survive higher AC overvoltages, reducing downtime

• Increased system reliability

• EPDM molded rubber deadfront construction
