Switchgear Sales & Service

Control of low and medium voltage power is vital to maintain safety and continuity. Switchgear can be deceptively benign. Testing components is the only way to ensure they will operate as designed when needed. Failure to function can be extremely dangerous and costly.

Without testing, switchgear is a dangerous unknown. Failure to trip can be catastrophic in loss of equipment, production and even loss of life. Once a defect is found, Longo is able to recondition the unit to like new condition.

Longo's extensive experience in the testing, repair and replacement of switchgear is a step above. To begin with, Longo has the expertise to tackle the repair of older units from sourcing impossible to find parts through reverse engineering parts and components.
