OEM / ODM Supported

Empower your brand with Naile Holding Group's comprehensive OEM and ODM solutions.
Backed by decades of manufacturing expertise in China's "Electrical Capital," we go beyond simple logo printing. From industry-leading heavy-duty ACBs (up to 8000A) and ultra-fast ATS, to a complete range of low-voltage components, our dedicated R&D team works closely with you to tailor technical specifications, product designs, and packaging. Engineered to meet strict IEC standards and proven in extreme environments across the Middle East and Africa, we help you build a dominant local brand with uncompromising quality and absolute margin protection.
IEC Standard

At Naile, quality and compliance are the cornerstones of our manufacturing excellence. We implement a rigorous, scientific quality management system—from premium raw material sourcing to precise production and final multi-stage testing.

All our core high and low-voltage products, including Air Circuit Breakers (ACB), Molded Case Circuit Breakers (MCCB), and Automatic Transfer Switches (ATS), are fully engineered and tested to comply with international IEC standards. This ensures optimal breaking capacity, absolute electrical safety, and seamless compatibility for global switchgear and panel-building projects. Every single unit delivers the long-term reliability that your critical distribution boards demand.
Saudi & Bahrain Project Experience

Proven Reliability in the Most Demanding MEA Environments
Tested in extreme climates and approved by top-tier engineering consultants, Naile Holding Group is the trusted power behind major infrastructure developments across the Middle East and Africa. We are exceptionally proud to supply heavy-duty ACBs and switchgear components for various massive commercial and infrastructure initiatives under the Saudi Vision 2030. In Bahrain, our products have successfully passed strict national utility pre-qualifications for critical distribution boards. Beyond the Middle East, our robust components continuously drive national grid reconstructions, heavy mining operations, and telecom backup projects across Nigeria, Kenya, Uganda, and Ethiopia. We deliver absolute reliability where it matters most.
One-stop Panel Components

Streamline your switchgear manufacturing with Naile's complete one-stop procurement solution.
We provide everything you need to build top-tier distribution boards, eliminating the hassle of dealing with multiple vendors. From industry-leading heavy-duty ACBs (up to 8000A), VCBs, and MCCBs for main incomers, to ultra-fast ATS, MCBs, SPDs, and Smart Meters for precise branch protection. By sourcing all your panel components directly from our automated factory, you ensure perfect system compatibility, significantly reduce your overall B.O.M (Bill of Materials) costs, and accelerate your project delivery.

Factory & Quality

Factory Image (ACB/MCCB Production Workshop)

Every ACB and MCCB leaving our facility passes through a fully automated intelligent manufacturing line — from contact assembly and bimetal calibration through computerised current injection testing and machine-vision inspection — before a human hand ever touches the shipping carton. Our production floor operates under a closed-loop quality management process whose batch traceability records link every finished unit back to its raw material intake, giving panel builders and switchgear integrators the documentation chain that government procurement authorities and independent commissioning engineers require when approving equipment for commercial building, municipal infrastructure, and energy storage projects. This is not contract manufacturing redirected through a trading company — it is vertically integrated source production, where the engineering team that designed the product controls the line that builds it.
Naile Electric — Source Factory for ACB, MCCB & Complete Switchgear Components

From the Gulf to sub-Saharan Africa, from Southeast Asia to Latin America, Naile Electric's export engineering team engages directly with panel builders, EPC contractors, and utility procurement professionals at the international industry events where real purchasing decisions begin. Our presence at EPES, WASIA, and other global electrical infrastructure exhibitions is not a branding exercise — it is a technical dialogue platform where our engineers discuss protection coordination studies, OEM customisation requirements, CB and TUV certification documentation, and factory audit scheduling with the procurement teams who build the switchgear that powers commercial cities. When you meet us at a show, you are speaking with the people who manage your production file, not a regional sales agent.
