Valiadis × CERB: Exclusive Partnership for Transformers, Generators & High‑Voltage Services

Meet us at HYDRO 2025
Thessaloniki • 22–24 October 2025 • HELEXPO • CERB Booth 131

Overview

Valiadis Hellenic Motors is pleased to announce its exclusive partnership with CERB (Central Energy Repair Base) — a European leader in testing, repair, overhaul, and manufacturing for transformers, hydro‑/turbo‑generators, rotating electrical machines, and high‑voltage equipment. Together we provide an end‑to‑end offering, from electric‑motor manufacturing (Valiadis) to accredited high‑voltage diagnostics, rewinding, balancing, field services, and transformer/generator refurbishment (CERB).

Why this partnership matters

• One accountable team: Motors, transformers, generators, drives, and site services under a single coordination.

• Depth & scale: Heavy‑industry workshops, accredited labs, and mobile teams for rapid deployment.

• Quality you can verify: EN ISO/IEC 17025 high‑voltage testing; proven procedures for diagnostics and acceptance.

Joint capabilities (highlights)

• High‑Voltage Testing (EN ISO/IEC 17025): type/routine tests, partial discharge, insulation diagnostics.

• Transformers: repair/refurbishment & manufacturing; dielectric oil processing; OLTC service & upgrades.

• Generators (hydro/turbo): rewinds, rotor/stator/core repairs, uprates, commissioning/on‑site start‑up.

• Rotating machines (LV/MV/HV): rewinds, dynamic balancing & alignment, vibration analysis, condition monitoring.

• Field & outage services: inspection, troubleshooting, emergency repair, retrofits and upgrades.

• Precision machining & materials QA: shafts/housings, tight‑tolerance fits; metals testing & failure analysis.

• Heavy logistics: engineered transport for large electrical equipment.
