What ENTEC Electric & Electronic does

ENTEC Electric & Electronic (인텍전기전자) is a South Korean manufacturer of medium-voltage power distribution equipment founded in 1996 and headquartered in Hwaseong-si, Gyeonggi-do. The company designs and produces solid insulated switchgear (SIS/D-SIS), gas insulated switchgear (C-GIS), reclosers, load break switches, ring main units, fault interrupters, DC traction power equipment including high-speed circuit breakers (HSCB), and Q-class DC circuit breakers for nuclear power plants, alongside a proprietary ARGOS distribution automation/SCADA software platform and an ETR series of protection relays and RTUs. Its core technology differentiator is HCEP (Hydrophobic Cycloaliphatic Epoxy) solid insulation, marketed as an environment-friendly replacement for SF6 gas, paired with a Permanent Magnetic Actuator mechanism rated for 40,000+ operation cycles.

The company sells through dedicated sector-specialized enterprise field sales teams (Power, Railway, Civil, Overseas Business Division), supplying direct to Korean monopoly buyer KEPCO and to Seoul Metro, with international export reach extending to over 50 countries including past project references at Taiwan Power, BESCOM (India), and PEDEE (Syria). Revenue is generated predominantly through hardware sales across four equipment streams — power T&D, metro/railway, power IT/SCADA, and aftermarket service — under a quote-based B2B pricing model with no public disclosure of list prices.

Product certifications and patent portfolio (16+ registered patents, ISO 9001 since 1997, ISO 14001 since 2017, Q-class nuclear certification, KT Mark, KEPIC, World-Class 300 designation from the Korean Ministry of Knowledge Economy in 2011) underpin credibility in regulated utility procurement. ENTEC operates as an independent private corporation with no disclosed parent company, institutional investors, or M&A activity in the source material.

The company produces solid and gas-insulated switchgear, reclosers, load break switches, DC high-speed circuit breakers for metro/railway traction systems, Q-class DC circuit breakers for nuclear power plants, and integrated Power IT/SCADA systems including protection relays, RTUs, and the proprietary ARGOS distribution automation platform.

Product overview

ENTEC Electric & Electronic (인텍전기전자) is a South Korean manufacturer of medium-voltage power distribution and transmission equipment serving the power transmission & distribution, metro/railway, nuclear power plant, and power IT sectors. The product portfolio centers on solid insulated switchgear (SIS/D-SIS), gas insulated switchgear (C-GIS/GIS), and DC protection systems, all designed around HCEP (Hydrophobic Cycloaliphatic Epoxy) insulation technology as a SF6-free alternative. The core offering is organized across five business segments: (1) Overhead Distribution — Solid/Gas Reclosers, Load Break Switches, Fault Interrupters, and Capacitor Switches; (2) Underground Distribution — Solid/Gas Pad Mount Switchgear, Ring Main Units (SRMU/GRMU), and Secondary Switchgear (ENSIS); (3) Substation — SIS, D-SIS (draw-out), C-GIS, and Compact Secondary Substation (CSS); (4) Metro/Railway — DC Switchgear (ETGR), High-Speed Circuit Breakers (HSCB/EDB), DC Disconnectors, Load Break Switches, Voltage Limiting Devices, Silicon Rectifiers (ETSR), Railway Outdoor CBs, and DC ACBs; and (5) Nuclear Power — Q-class DC Circuit Breaker (ETNB). All product lines are complemented by an integrated Power IT ecosystem including microprocessor-based protection relays (ETR500, ETR300-R, ETCPU, ETCCU), Remote Terminal Units (ETRTU 3000), and the proprietary ARGOS SCADA/Distribution Automation System, which supports DNP 3.0, IEC 60870, IEC 61850, and MODBUS communication protocols. ENTEC positions its solid insulation technology as an environmentally friendly alternative to traditional SF6 gas insulation, reducing maintenance requirements and eliminating gas leakage risks.
