Electrical Circuit
Reliability in any challenging weather conditions


Reliability in any challenging weather conditions

Sometimes, small devices can significantly impact electrical network’s reliability. That's why at CO7 Technologies, we take reliability, safety, and quality very seriously. For the past 30 years, our V-Rupt fused cutout has been extensively deployed in the most challenging conditions. Designed to be safe and unbreakable, it withstands the climate stress like wide temperature variations and freeze/thaw cycles. The V-Rupt consistently delivers exceptional performance in all extreme conditions.


Powering Grid Awarness

LineWatch low/medium voltage sensing and monitoring devices provide utilities and Distributed Energy Ressources (DER) with the situational awareness they need to address a number of smart grid applications including substation monitoring, grid automation, asset management, fault detection, non-technical losses, capacitor bank monitoring, and Volt/VAR optimization/conservation voltage reduction.


LineWatch devices are easily and quickly installed using a hotstick and can deliver data over any communication platform to existing SCADA and other databases or to its headend data collection engine.
