Does Entogo offer OEM, private-label or white-label transformer manufacturing?

Yes. Entogo is an OEM and contract manufacturing partner for transformers, switchgear, packaged substations and power-distribution equipment. It manufactures to a customer’s drawings and specifications (build-to-print) or to its own designs, and produces equipment under the customer’s brand, nameplate and documentation for private-label / white-label programs. Every engagement opens under a non-disclosure agreement and is confirmed in a written manufacturing agreement.

Can Entogo build transformers and switchgear to our drawings and specifications?

Yes — build-to-print manufacturing to your drawings, ratings, bill of materials and tooling is the core of the program. If there is no finished drawing yet, Entogo’s engineering team co-engineers the design from your requirement and one-line, to ANSI/IEEE or IEC, through drawing approval and factory acceptance testing.

What can Entogo manufacture?

Pad-mounted, dry-type, liquid-filled distribution and power transformers (to roughly 10 MVA / 36 kV class); packaged and unit substations to 34.5 kV; medium-voltage switchgear (15/27/38 kV class); low-voltage switchgear and switchboards to 6000 A; and battery energy storage and EV-charging equipment — all from one ~20,000 m² vertically integrated source factory and one quality system.

What are Entogo’s OEM lead times?

Standard equipment — including transformers, substations and switchgear — ships in an average of 12 weeks. When a product requires new UL or other North-American certification before it can energise, delivery is guaranteed within 36 weeks. Because Entogo owns its source factory and runs a vertically integrated supply chain, it is not waiting in the one-to-four-year merchant-market queue.

Where is Entogo based and where do you manufacture?

Entogo is a Canadian company headquartered in Toronto, Ontario, with North-American points of contact, documentation and accountability. It manufactures in its own ~20,000 m² vertically integrated source factory, which gives it direct control over production scheduling, quality and lead time.

Do you work with manufacturer’s sales representatives and distributors?

Yes. Entogo works with electrical sales representatives and distributors as a line-card manufacturing partner — offering open territories, a product line with a real lead-time advantage to sell, sample and FAT support to win the first account, engineering and quotation support behind every RFQ, and a private-label option. Terms are confirmed in a written representation agreement.

How do you protect our designs and intellectual property?

A non-disclosure agreement is in place before any drawings are exchanged. Build-to-print work keeps your design, tooling and brand yours; nothing is offered to other buyers. The full scope, ownership and confidentiality terms are documented in a written manufacturing agreement signed by Entogo.

What is the minimum order quantity, and can we start with a pilot?

Entogo welcomes first-article and pilot orders so a partner can verify fit, finish and field performance before committing to volume — a low-risk way to prove the design and earn the first delivered reference. Minimum quantities depend on the product type and configuration and are confirmed per project; there is no one-size-fits-all minimum.

OEM & contract manufacturing

Your transformer manufacturing partner — built to your spec, or your brand.

A Canada-based OEM and contract manufacturer for transformers, switchgear, substations and power-distribution equipment. Build to your drawings or ours, under your brand if you want one — with the factory, the quality system and the lead times the merchant market can no longer offer.

Overview

Entogo is a Canada-based OEM and contract manufacturing partner for transformers, switchgear, packaged substations and power-distribution equipment. It builds to a customer’s drawings and specifications (build-to-print) or to its own designs, and offers private-label / white-label production under your brand. The program is backed by Entogo’s own ~20,000 m² vertically integrated source factory, engineering and design support, an ISO 9001 / ISO 14001 / IATF 16949 quality system, and UL, CSA, CE and IEC CB Scheme marks held across product lines. Transformer and distribution equipment is designed and built to ANSI/IEEE and IEC standards, with UL (cULus) / CSA certification supported on request. Standard equipment ships in an average of 12 weeks — guaranteed within 36 weeks even when new North-American certification is required — versus the one-to-four-year merchant-market backlog. Entogo also works with electrical sales representatives and distributors as a line-card manufacturing partner, under NDA and a written agreement.

Why partner with Entogo

A manufacturing partner, not a fixed catalogue

For brands, EPCs and reps, the bottleneck is no longer the design — it is finding a factory that can build it, certify it and deliver it on a real schedule.

Capacity while the market waits

Entogo manufactures in its own vertically integrated source factory — not the merchant queue. Standard equipment ships in an average of 12 weeks, versus the one-to-four-year backlog now common across the transformer market.

Build to your drawings or ours

Build-to-print to your specifications and tooling, or co-engineered from a requirement. Either way you get a manufacturing partner, not a fixed catalogue — there is no product line you have to bend your project around.

A North-American partner

A Canada-based company headquartered in Toronto, with North-American points of contact, documentation and accountability — so reps, EPCs and brands have someone to hold to the agreement.

Certification supported

Transformers and distribution equipment are designed and built to ANSI/IEEE and IEC standards, with UL (cULus) / CSA certification supported on request and delivery still guaranteed inside the lead-time envelope.

Engineering on your side

Electrical and mechanical engineering support through specification, drawing approval, factory acceptance testing and documentation — the work that turns a requirement into a buildable, inspectable product.

One factory, full breadth

Transformers, packaged substations, switchgear and power-distribution equipment from one quality system and one schedule — useful when a project, brand or line card needs more than a single product type.

How it works

From first contact to volume production

A clear, low-risk path: prove the design on a first article, confirm it on a pilot, then scale — every step documented.

Share the requirement & sign an NDA

Send drawings or a specification, target ratings, quantities, destination and timeline. An NDA is in place before any design detail is exchanged.
Engineering review & quotation

Entogo reviews the scope, confirms the standard and configuration, and returns a technical and commercial quotation — co-engineering the design where there is no finished drawing yet.
First article / sample & FAT

A first article or sample is built and verified by factory acceptance testing — remote or witnessed — so the design and quality are proven before any volume commitment.
Pilot production order

A low-risk pilot or initial batch confirms fit, finish and field performance, and gives the first delivered reference.
Volume production & QC

Scheduled production under the ISO 9001 system, with in-process inspection, burn-in testing and milestone updates against the agreed delivery window.
Delivery & lifecycle support

Shipment, documentation and certification support, followed by warranty, spare parts and technical support for the life of the equipment.

Lead times

Delivered on a real schedule

European-standard (IEC/CE) catalogue equipment: ~12 weeks (average)
Transformers & substations (standard build): ~12 weeks
Switchgear & distribution equipment: ~12 weeks
Products requiring new UL / North-American certification: within 36 weeks (guaranteed worst case)
