EVOSYS delivers utility-grade, “made-to-order” Panel Building Services specifically engineered for the rigorous demands of the UK’s EHV, HV, and MV networks. We bridge the gap between complex electrical design and physical asset deployment, providing a centralized solution for the assembly, wiring, and factory testing of critical substation secondary systems.

Our manufacturing process is centred on high-fidelity workmanship, electromagnetic compatibility (EMC), and operational durability. By housing your protection, control, and communication assets in our bespoke enclosures, we ensure your infrastructure remains resilient, organized, and ready for rapid site deployment.

Protection & Control (P&C) Panels

We specialize in the assembly of sophisticated P&C suites that serve as the brain of the substation. Our panels are designed to house advanced numerical relays and logic controllers for overcurrent, differential, and distance protection.

  • Precision Wiring: High-density, logical wiring with clear ferruling and terminal segregation.
  • Logic Integration: Factory-wired schemes for automated interlocking and breaker-fail coordination.

SCADA, Automation & Telecom Racks

EVOSYS builds dedicated enclosures for the “nervous system” of the digital grid. We integrate multi-vendor RTUs, Gateways, and HMI Servers into thermally managed, secure racks.

  • Network Infrastructure: Specialized assembly for MPLS routers, SDH/PDH nodes, and managed Ethernet switches supporting HSR/PRP redundancy.
  • Fiber Management: Integrated high-density Optical Distribution Frames (ODF) for secure fibre patching and splicing.

Mission-Critical Telecom Panels

EVOSYS delivers specialized design and assembly for dedicated Telecommunication and Network Panels, engineered to maintain 99.99%+ availability in harsh electrical environments.

  • Backhaul & Gateway Racks: Custom integration of MPLS routers, SDH/PDH multiplexers, and DWDM equipment featuring optimized thermal management.
  • Fiber Management: Integration of high-density Optical Distribution Frames (ODF) and splicing trays for secure fiber-optic termination and patching.
  • Teleprotection Suites: Specialized panels housing C37.94 interfaces and Pilot Wire signalling equipment, featuring dedicated auxiliary power failover logic to ensure protection continuity.

Marshalling Kiosks & Distribution Boards

We design and build robust outdoor and indoor marshalling solutions to simplify field-to-control room connectivity.

  • AC/DC Distribution: Bespoke distribution boards featuring essential/non-essential load segregation and discrimination.
  • Interface Kiosks: Hardened outdoor enclosures for primary plant signal aggregation, ensuring IP-rated protection against harsh environments.

Auxiliary & DC Power Systems

To guarantee 99.99%+ availability, we build integrated DC power panels housing battery chargers, UPS units, and monitoring systems. These units are engineered to provide the fail-safe backbone required for protection tripping and telecontrol during black-start conditions.

Quality Assurance & Factory Acceptance Testing (FAT)

Every panel leaving our facility undergoes a comprehensive FAT regime. We perform point-to-point continuity checks, insulation resistance (IR) testing, and protocol-level verification (IEC 61850, DNP3) using advanced relay test sets. Our handover includes full as-built schematics, wiring schedules, and certified test reports, significantly reducing on-site commissioning timelines.

By combining deep multi-vendor expertise with high-quality assembly standards, EVOSYS transforms complex secondary designs into reliable, site-ready assets.
