ENGINEERING & OEM SUPPORT

Design & Application Support for MV & HV Projects

XBRELE’s engineering team helps you match vacuum circuit breakers, vacuum contactors, embedded poles and transformers with your switchgear layout, standards and operating conditions — before the first batch enters production.

For many panel builders and OEM brands, the key challenge is not only sourcing components, but ensuring that interfaces, clearances and performance data align with real-world projects. XBRELE provides front-end engineering support so that drawings, specifications and assembly details are clarified before manufacturing.

Our engineers review your switchgear layouts (KYN28, KYN61, XGN, RMU, custom cabinets), environmental conditions (altitude, pollution level, ambient temperature) and standards (IEC / GB), then recommend suitable combinations of VCBs, VIs, contactors, embedded poles, insulation parts and transformers.

  • Review of panel drawings, busbar schemes and compartment layouts
  • Interface matching for handcart types, embedded poles and insulation parts
  • Adaptation for high-altitude, heavy pollution or harsh industrial environments
  • Retrofit guidance for replacing legacy VCBs / contactors with XBRELE equivalents

Typical workflow: you share project data and drawings → XBRELE proposes matched components and outline specs → both sides confirm interfaces and testing requirements → OEM production starts with clear technical targets.

TESTING & QUALITY

High-Voltage Testing & Quality Control for MV/HV Components

Every vacuum circuit breaker, vacuum contactor, embedded pole, insulation component and transformer from XBRELE is validated through a structured testing and quality control process, aligned with IEC and customer-specific requirements.

For MV and HV equipment, quality is defined by numbers: withstand voltage, partial discharge level, mechanical endurance, temperature rise and more. XBRELE operates dedicated labs for dielectric testing, routine checks and sampling inspection to keep these values under strict control.

Type & Routine Tests
Typical tests and controls
  • Power-frequency withstand and lightning impulse tests for VCBs and embedded poles
  • Partial discharge measurement (e.g. < 5 pC) for epoxy insulation and switchgear parts
  • Mechanical endurance tests for operating mechanisms and contact systems
  • Temperature rise and load tests for distribution transformers and high-current conductors
  • Incoming material inspection for copper, epoxy resin, laminations and auxiliary parts
  • Final routine tests with traceable records for OEM and utility projects

For critical projects, XBRELE can cooperate with third-party laboratories to carry out full type tests and issue independent test reports. Routine and sampling reports can be attached to each shipment as part of your QA documentation package.

EXPORT LOGISTICS & AFTER-SALES

FAQ

Frequently Asked Questions

What is the typical lead time for MV/HV components?

Standard components (VS1/ZN85 parts, conductors, insulation components) typically require 2–4 weeks. Series-specific assemblies and embedded poles generally require 4–6 weeks. Delivery time may vary depending on project size and testing requirements.

Can XBRELE support OEM development and custom specifications?

Yes. XBRELE provides OEM manufacturing for vacuum interrupter assemblies, embedded poles, copper conductors, insulation parts and breaker accessories. Drawings, samples or detailed specs are required for engineering evaluation before production.

Do you provide testing reports and documentation?

All shipments include dimensional reports, material documentation and routine test results. Type-test reports or additional testing (temperature rise, mechanical endurance, partial discharge) can be arranged upon request.

How is export packing handled for fragile MV/HV components?

Components are packed with moisture-proof, shock-absorbing materials along with palletizing or reinforced wooden cases. Container loading photos and packing lists are provided for all export orders.

What after-sales support is available?

XBRELE offers online support for installation/commissioning questions, spare parts supply, and clarification for wiring, mechanism adjustments and operating instructions. Response time is typically within 24 hours on working days.
