Product Description

Integrated Selling Points

Globally compliant with IEC 62271-200, IAC type-tested, IP4X (enclosure) / IP2X (door open). KYN28A-12 (12kV), KYN28-24 (24kV), KYN61-40.5 (40.5kV) cover mainstream MV grids in Southeast Asia, Africa, and South America.

Metal-clad withdrawable structure with five-interlock system ensures maximum operational safety. Cabinet uses ZAM steel with multi-bending process for high strength and corrosion resistance. All front-access operations support wall-mounted installation to save floor space.

Rated current from 630A to 3150A, short-time withstand up to 50kA. Wide temperature range (-40°C to +55°C) suits coastal humidity, high altitude, and dusty sites. SF6-free vacuum interruption technology is eco-friendly.

Flexible breaker options (VS1, VD4, VEP, etc.) with modular design enable quick unit replacement within 1.5 hours. Self import/export license and OEM customization available.

Application Scenarios

Power generation & substation: Ideal for power plants, secondary substations, and transformer (100kVA-2500kVA) integration. KYN61-40.5 excels in 35kV-class substations and hydropower systems.

Industrial & commercial distribution: Widely used in metallurgy, chemical, mining, and shipbuilding for motor control and protection, ensuring stable power under harsh conditions.

Renewable energy & infrastructure: Suitable for PV station collection, urban loop networks, and building distribution. Supports smart monitoring for real-time power quality and remote O&M.

EPC projects: Proven in overseas 33/11kV substation projects (e.g., 176 units KYN28A-12 in Bangladesh). Reliable choice for turnkey contractors.

Frequently Asked Questions

Q1: Does it fully comply with IEC 62271-200? Can you provide test reports?
A: Yes. Type test certificates (including IAC AFL ratings) and routine test reports (withstand voltage, resistance, interlock checks) are available, with serial numbers matching each shipped unit.

Q2: Which voltage does each model suit?
A: KYN28A-12 → 12kV systems; KYN28-24 → 24kV systems; KYN61-40.5 → 35kV/40.5kV systems. Choose based on your project's nominal grid voltage.

Q3: Can you supply 60Hz and fit specified breaker brands?
A: Yes, both 50Hz and 60Hz available. Breakers can be VS1, VD4, VEP, or vacuum contactors per your request.

Q4: What is the mechanical endurance?
A: Typically 50,000+ operations. For frequent daily switching or auto-reclosing, please confirm M2 endurance level when ordering.

Q5: Packaging, lead time, and MOQ?
A: Export-grade wooden crates for sea freight. Monthly capacity 500+ units. Lead time depends on quantity/customization. MOQ negotiable – wholesalers and project buyers welcome.

Q6: Smart monitoring and remote O&M?
A: Optional sensors for temperature and partial discharge, plus IEC 61850 protocol support for remote management and unmanned operation.
