150kVa Dry Type Transformer

Manufactured by CHBEB (Beierbian Group Co., Ltd.), a power equipment producer serving 17+ countries since 1956. This 150 kVA dry type transformer is built for facilities that need a maintenance-free, fire-safe alternative to oil-filled units - commercial buildings, light industrial plants, hospitals, and indoor substations where liquid-filled equipment is restricted or undesirable.

Every unit is engineered around epoxy resin vacuum-casting, tested to IEC 60076-11 before it leaves the factory, and backed by a 3-year whole-machine + 2-year components warranty with lifetime technical support.

• Configured to order, not pulled off a shelf - voltage, frequency, and enclosure matched to your grid and site (full options below).
• 100% factory tested before shipment, not sample-checked (details under Quality).
• Third-party verified, not self-certified (certifications listed below).

Exact loss values, impedance voltage, sound level, and dimensional drawings for your configuration are provided with the formal quotation and Factory Acceptance Test (FAT) report. IEC 60076-11 is the standard baseline; GOST-R and ANSI/IEEE C57.12.01 compliance are available on request for CIS and North/South American markets respectively.

CHBEB's quality control follows a four-stage process, each tied to a named international or national standard - not an internal-only checklist:

• Incoming inspection - silicon steel core loss and insulation paper heat-resistance rating, per GB/T 2521 and IEC 60641.
• In-process control - core lamination precision (±0.02mm) and inter-turn winding voltage withstand, per JB/T 501 and IEEE C57.12.00.
• Final inspection - no-load loss (≤102% of rated value) and partial discharge (≤5 PC), per IEC 60076 and GB 1094.11.
• Third-party verification - independent testing by KEMA (Netherlands) and CQC, alongside the certifications listed further below.

Core raw materials are sourced from named suppliers: Baowu Steel (Grade A silicon steel) and DuPont Nomex® / Vishay® insulation materials.

Our quality team runs 30+ dedicated inspectors, each completing 200+ hours of specialized training annually and certified to CNAS standards.
