"DESIGNED WITH THE LINEMAN IN MIND"
Much safer for linemen and Public (reasons listed below)
Primary and secondary compartments completely separate yet integral
presents a much lower profile near roads reducing chance of being hit by vehicles
Touch safe roomier and safer layout*
In most cases low voltage compartment will see only 240V circuits.
Low voltage circuits can be worked on while de-energized. (1)
Multipoint voltage check in secondary cabinet to ensure system condition prior to entering low voltage compartment. Voltage indicating LED with high impedance test points and breaker remote operating handle at the door to ensure circuit is de-energized prior to breaking the plane of the cabinet.
Caution: Ensure all local and industry applicable utility safety procedures are followed
Ensure LED is lit showing voltage is present prior to opening the breaker
Observe LED lights out
Lift dust cover from test points
Test for voltage at the high impedance test point in top left corner of cabinet to confirm no voltage on secondary lugs
Ground secondary to ensure there is no back fed power (alternate generated power from solar panels, generators, or any other sources)
80% of all transformer failures are caused by low voltage events (lightning or fault/surges).
Arresters protect from lightning and switching surges. Units protect core/coil and personnel up to multiple 140kA strikes, vs. more common units good for only one 40kA. The unit does not require a special metal box for personnel protection in case of failure (robust design plus handles multiple 140kA strikes, with a 10 year warranty).
Current limiting breaker protects from high I2T levels (1/2 cycle or less vs. legacy 6 cycle interruption) during fault conditions, reducing potential high arc flash energy levels
Provides personnel and system protection between the unit and load with full range current-limiting circuit breaker, dramatically decreases the I2T should a fault occur.*
Window between primary and secondary to allow visible confirmation of ground connection*
Ground sleeve has separate compartments preventing low voltage cables from coming in contact with high voltage cables.
Touch safe(may be class A which means no dress up to work on product)

Lift-up cover with mechanical assist
Lowers the risk of back injuries; lift starts at 30” instead of 8” like legacy doors on sectionalizing cabinets. Think ergonomics and the twisting and lift for standard legacy installations.
Mechanical assist makes opening the cover easy, again lowering the risk of back injuries
Lift cover provides better access and clearance while pulling cables in during installation
One integrated unit results in fewer trenches to traverse during installation.
Less hoist movement and lifting.
Dramatically reduces installation space requirements
May reduce ROW or easement costs
One less transformer (less material cost and material handling costs)
One less ground sleeve (less material cost and material handling costs)
Less ground connections (less material cost and material handling costs)
Less ground wire (less material cost and material handling costs)
Fewer ground rods (less material cost and material handling costs)
Less primary duct (less material cost and material handling costs)
Less primary cable (less cost and labor to cut, carry, laydown, terminate)
Fewer elbow seals (less cost and labor to install)
Fewer elbows (less labor, reduces chance of human error)
Less trenching (lower equipment, cable location costs and labor)
No secondary pedestal required
High flash point, seed-based biodegradable dielectric fluid extends core/coil life 5 - 8 times.
Core style with interlaced winding's improves lightning surge protection.
High energy lightning arresters (140 kA)
Surge layering on the high side windings
Current-limiting fusing dramatically decreases the I2T available should fault occur, preventing tears and mechanical stresses to insulating materials and damage to the coil due to fault traveling through the unit to the bay-o-net fuse.
More than twice the cooling than required and louvers provide addition heat dissipation.
Fewer elbows installed reduces potential failure points
Low side breaker eliminates the need for a Bay-O-Net registered trademark of RTE/EATON.
12-ga. vs 14-ga. cabinet
*The POWERMATRIX meets or exceeds DOE2016 efficiency standards.
*In small load applications <10kVA loads the unit is 30% - 70% more efficient than standard 10kVA or larger units.
