What Coelme does

COELME-EGIC is a privately held Italian-French manufacturer of high-voltage electrical equipment, founded in Italy in 1950 and operating in conjunction with its French subsidiary EGIC (headquartered in Villeurbanne). The company specializes in disconnectors (isolators), switchers, load-break switches, earthing switches, motor and manual operating mechanisms, HVDC equipment, and—most recently—F-gas-free vacuum circuit breakers, spanning voltage classes from 12kV to 800kV. The technology portfolio includes patented innovations such as the ICS® wireless current sensor, AOM autonomous solar/battery-powered operating mechanism, DOM IEC 61850-compliant digital mechanism, and monitorWise® battery-free wireless condition-monitoring platform. The product set is complemented by specialized components for railway electrification and the ITER fusion research project.

The company operates a project-based B2B sales model, manufacturing custom-engineered equipment to specification for electrical transmission and distribution system operators, railway infrastructure managers, and large industrial clients in over 40 countries. Revenue is generated through direct sales from the two manufacturing facilities in Italy and France, supplemented by an exclusive channel partnership with Southern States LLC for the USA/Canada/Antigua/Barbuda and a wholly-owned Mexican subsidiary (Coelmegic México). Pricing is quote-based and not publicly disclosed; supplementary revenue comes from after-sales maintenance, repair, overhaul, upgrading, thermographic analysis, and training services.

The customer base includes national utilities and TSOs such as TERNA, RTE France, EDF, E-Distribuzione, RFI, SNCF Réseau, 50Hertz/Tennet/Transnet, SONELGAZ, UKRENERGO, FURNAS/CHESF, and Saudi Electricity Company/Aramco. Go-to-market relies on direct enterprise sales, a global network of 50+ agents and distributors, and participation in major trade shows (Cigré, InnoTrans, Verkosto). The company holds ISO 9001/14001/45001 certifications, Ecovadis Silver Medal (2025), and UNI/PdR 125:2022 gender equality certification, and is qualified by utilities across Europe, MENA, the Americas, and Asia.

Products and services

• Centre-break Disconnector (CBD) Substation disconnector with two coordinated arms that close the circuit at a point approximately halfway between the insulators; the most common disconnector type worldwide due to its simple and economical design. Sold to utilities and TSOs/DSOs for substation safety isolation.
• Double-break Disconnector (TCB and STC) Substation disconnector with a central moving arm that closes the circuit on two fixed contacts, available in TCB (simple/economical) and STC (high short-circuit performance) variants. For utility and industrial substation use.
• Vertical-break Disconnector (SHD and SLOB) Substation disconnector with an arm moving in the plane of the insulators and closing on a fixed lateral-insulator contact; SHD variant for standard duty, SLOB variant for high short-circuit performance. Sold to utility and industrial customers.
• Pantograph Disconnector (VR2D) Pantograph disconnector with two articulated semi-arms moving vertically in the plane of the insulators and closing on an overhead busbar fixed contact, providing wider contact area for flexible-busbar substations. Used by utility TSOs/DSOs.
• Semi-pantograph Disconnector (SSP) Semi-pantograph disconnector with an articulated arm moving vertically in the plane of the insulators and closing on an overhead busbar fixed contact, minimizing substation surface area and allowing maintenance without de-energizing the busbar. Sold to utility TSOs.
• Knee-type Disconnector (OH) Knee-type disconnector with an articulated arm moving horizontally in the plane of the insulators, closing on a fixed lateral contact; reduces phase-to-phase distance and footprint in the open position. The OH-EE 500 kV variant is qualified for HVDC substations.
