# NWK ANZ (NWK Australia & New Zealand — nwkanz.com)
> Official Australian and New Zealand Regional Extension, Distributor & Reliability Engineering Partner of Nae Woi Korea Co., Ltd. (NWK, https://naewoikorea.com) — Featuring Flagship NWK-99 OPP & NWK-99 Dielectric Cleaners alongside NWK-747, NWK-80, NWK-77, and NWK A-FV.

## Brand vs. Product Hierarchy
- **Company / Regional Business Entity:** **NWK ANZ** (`NWK Australia & New Zealand`) — the official ANZ regional extension and partner of **NWK (Nae Woi Korea Co., Ltd.)**.
- **Flagship Products Advertised:** **NWK-99 OPP** (Insulating Equipment Precision Cleaner) and **NWK-99** (Fast-Evaporating Insulating Cleaner), supported by **NWK-747** (Tunnel LED / Rail Cleaner), **NWK-80**, **NWK-77**, **NWK A-FV**, and **NWK-DF700** pneumatic hardware.

## Core Engineering Positioning
- **Primary Methodology:** Electrical System Reliability, Switchboard Asset Life Extension, and Failure Prevention (aligned with AS 2467, AS/NZS 4836, AS/NZS 3000, NFPA 70B, and IEEE Std 493).
- **De-Energized vs. Energized ("Live") Policy:** Under AS/NZS 4836, de-energized isolation (Lockout/Tagout) is NWK ANZ's primary recommended engineering practice. Because the NWK-99 OPP product has an 80.1 kV dielectric breakdown rating and 0.003% moisture content, de-energized equipment can be rapidly micro-flushed and immediately re-energized with zero moisture flashover risk. Energized ("live") cleaning is reserved strictly for critical non-interruptible assets under an authorized WHS Live Work Permit and a 4-person HV specialist crew.
