SEC. 03 — Why 1 Quantum
Supply built around the specification
A Shenzhen-based trading and automation company supporting industrial buyers with materials, equipment and the technical paperwork that goes with them.
Direct China export
Products exported directly from China to India and other overseas markets, with import & export handled in-house.
Specification-led supply
Enquiries start from grade, standard, dimensions and tolerances — not a generic product name.
Technical documentation
Datasheets, grade references and manuals organised by product, so engineering teams can compare.
Structured RFQs
Quotation requests capture quantity, destination and attachments up front, reducing back-and-forth.
Installation & maintenance
General mechanical equipment installation and maintenance of electronic & mechanical equipment.
SEC. 04 — Electrical steel spotlight
CRGO & CRNGO, read like an engineer
Grain-oriented and non-grain-oriented electrical steel for the magnetic cores of transformers, motors and reactors. Decode a grade, compare reference values, then request the exact specification.
P-02.1 · CRGO / GO
Grain-oriented
Magnetic properties optimised along the rolling direction — for cores where flux follows one path.
- Power transformers
- Distribution transformers
- Reactors
- Instrument transformers
P-02.2 · CRNGO / NGO
Non-grain-oriented
Near-uniform magnetic properties in all directions — for rotating machines where flux direction changes.
- Large motors
- Generators
- Rotating machines
- Voltage regulators
