What SEL does

SEL S.p.A. is an Italian manufacturer of medium voltage (MV) electrical switchgear founded in 1988 and headquartered in Lamporecchio, Province of Pistoia, Italy. The company designs, develops, and manufactures its entire product range in-house, spanning air-insulated switchgear (AIS), gas-insulated switchgear (GIS), ring main units (RMUs), and pole-mounted switches for applications from 7.2kV to 40.5kV. Core technology is built around vacuum circuit-breaker technology housed in hermetically welded, sealed-for-life stainless steel tanks with solid-insulated busbars, and the portfolio has recently expanded to include SF6-free alternatives using clean dry air as the insulating medium and a patented three-position switch disconnector (IMS SF6 Free) for vacuum-based interruption.

The product lineup comprises the TPS family of AIS modules, the TPR6 series of GIS RMUs (including 24kV, 36kV, 40.5kV HP, and 36kV HP PLUS primary distribution variants reaching 2000A and 31.5kA short-time withstand), the PLS pole-mounted switch, and the SF6-free F-TPS Air, TPRAir, and IMS SF6 Free modules launched in 2025. The company is actively repositioning its catalog to address the EU regulatory phase-out of SF6 in MV equipment. All manufacturing is TUV-certified under ISO 9001:2015, with additional ISO 14001 environmental and ISO 45001 health-and-safety certifications, and products are type-tested in international laboratories.

SEL sells through direct commercial enquiries ([email protected]) and a dedicated after-sales service channel, targeting utilities, industrial operators, renewables and power generation projects, transport and infrastructure deployments, and power and energy customers worldwide. Revenue is generated through configured hardware sales of MV switchgear equipment to enterprise customers, with no public pricing, channel partner model, or e-commerce offering disclosed. The company does not provide employee-level ownership or financial information in its public materials.

Core offering

SEL designs and manufactures medium voltage switchgear and related electrical distribution equipment, including air-insulated switchgear (AIS), gas-insulated switchgear (GIS) ring main units, and pole-mounted SF6-insulated switch disconnectors. Products span secondary and primary distribution, from 24 kV up to 40.5 kV, and the company has introduced SF6-free product lines using dry-air insulation and vacuum interruption for utilities, industry, renewables, and infrastructure applications.

Product overview

SEL S.p.A. is an Italian manufacturer of Medium Voltage (MV) switchgear, Ring Main Units (RMU), and electrical distribution equipment. The product portfolio consists of two main switchgear families: AIS (Air Insulated Switchgear) and GIS (Gas Insulated Switchgear), with both traditional SF6-insulated and newer SF6-free (eco-friendly) variants. The TPR6 series (TPR6 24, TPR6 36, TPR6 HP, TPR6 HP PLUS) provides GIS RMU and switchgear solutions for secondary and primary distribution from 24kV to 40.5kV. The TPS series offers AIS solutions for secondary distribution up to 24kV. The PLS is a pole-mounted switch for overhead lines. The SF6-free lineup includes F-TPS Air, TPRAir, and the patented IMS SF6 Free three-position switch disconnector, all using dry air insulation and vacuum interrupters for decarbonization. Products range from 200A to 2000A rated current and up to 31.5kA short-time withstand current.
