Model meaning

Conditions of Use

Let’s cut to the chase on what this KYN61-40.5KV Switchgear can handle—no jargon, just clear specs for your procurement checks:

Operating Environment Conditions

Ambient Temp: Tops out at +40°C, dips as low as -15°C—works in most indoor climates.

Humidity Rules: Daily average ≤95%, monthly average ≤90%; water vapor pressure maxes at 2.2kPa daily, 1.8kPa monthly—holds up even in damp spots.

Altitude: Max 1000 meters above sea level (any higher, let’s chat).

Quake Resistance: Takes ≤8-degree Richter scale quakes—stable where it counts.

Air Quality: Needs air free of corrosive/flammable gases, excess dust, water vapor, or heavy pollutants—keeps internal parts from wearing out fast.

Vibration: Installation site can’t have severe shaking—protects delicate components.

If your site’s conditions go beyond what GB3906 outlines (like higher altitude or harsher air), just reach out to Welcome (Wenzhou) Electric Co., Ltd. We’ll work with you to hash out special arrangements that fit your project.

Whether you’re procuring for a substation, power plant, or industrial site, knowing use conditions of KYN61-40.5KV Switchgear helps you pick gear that lasts—and we’re here to make sure it’s a perfect match.

Main Characteristics

1. Smart Cabinet & Breaker Design

The KYN61-40.5KV Switchgear’s built with an assembly structure—easy to put together and tweak if needed. The circuit breaker uses a floor-type handcart setup, so it’s stable but still flexible for maintenance.

2. Top-Notch VCB Insulation

We’ve fitted a brand-new composite insulation vacuum circuit breaker here. It’s not just reliable—swap it out easily if you need to, and it plays nice with other components (no compatibility headaches for your procurement team).

3. Smooth Handcart Operation

The handcart frame has a screw-nut propelling mechanism—moves super easily, no heavy lifting. And it stops misoperation from messing up the pushing structure, so you don’t deal with costly damage down the line.

4. Door-Closed Operation

All controls work even when the cabinet door’s shut—no need to open it up to tweak settings. Way safer for your team and way more convenient day-to-day.

5. “Five Protection” Mechanical Lock

Mandatory mechanical locks link the main switch, trolley, and cabinet door—hits that critical “five protection” safety function. No accidental toggles or unsafe access, period.

6. Spacious Cable Room

The cable room’s roomy enough to hook up multiple cables—no cramming, no messy wiring. Perfect for sites that need to expand or have complex cable setups.

7. Quick Earth Switch

Comes with a fast earth switch for grounding and line short-circuit scenarios—responds in a flash when you need it, adding an extra layer of safety.

8. Solid Protection Ratings

Shell protection hits IP3X (keeps dust and small objects out), and when the handcart room door’s open, it stays at IP2X—tough against whatever indoor environments throw at it.

9. Full Compliance

Meets all the key standards: IEC62271-200, GB 3906-2006, DL/T 404-2007, plus references international IEC 298. So you’re sourcing gear that’s certified, reliable, and up to global benchmarks.

At Welcome (Wenzhou) Electric Co., Ltd, these characteristics aren’t just specs—they’re built to make your procurement and operation smoother. Whether you’re buying in bulk for a substation or customizing for an industrial site, this switchgear delivers on safety, flexibility, and durability.

Indoor Switchgear: Operating Conditions

Let’s cut to the chase—here’s what our indoor KYN61-40.5KV Switchgear handles, right in line with IEC standards, for your procurement needs:
