Wone Store
2yrs + staff 1000+m² US$300,000,000+ China

  1. Southeast Asia Market Pain Points & EVT Solutions

​Pain Points

​EVT Solutions

High Temperature & Humidity

IP67 Protection + Silicone Potting:​ Withstands 40°C/95% RH environments, increasing lifespan by 50%.

Frequent Grid Fluctuations

Class 0.2 Accuracy + Wide Input Range (110kV-500kV):​ Adapts to unstable grids.

Difficult Island Deployment

Modular Design (<20kg/unit):​ Enables helicopter airlifting, reducing remote area installation costs.

Combustible Traditional Transformers

Dry-Type Solid-State Design:​ Eliminates fire risk (Certified to IEC 61869-11).

Smart Grid Integration Needs

Digital Output (IEC 61850-9-2LE):​ Seamless integration with SCADA/EMS.

Solution for Medium-Voltage Motor Control and Protection Using Vacuum Contactor-Fuse (VCF) in a Coal Conveying System
Project BackgroundA coal conveying system comprises 15 belt conveyors driven by medium-voltage motors. The system operates under complex conditions, with motors often subjected to heavy loads and frequent starts. To address these challenges and achieve effective control and reliable protection during motor startup, the project comprehensively adopts Vacuum Contactor-Fuse (VCF) combination devices for the 6kV medium-voltage motor power distribution. This solution details the technical features,
ABB Vacuum Contactor KC2 Power Supply System Technical Transformation Plan
Issue Overview​The 10kV air compressor starting system of a company utilizes the ABB vacuum contactor KC2 as the control component for the operating circuit. The dedicated wide-voltage power supply module paired with this contactor presents the following issues:​Frequent failures: The power supply module fails to properly transition the voltage from 300V to 12V, resulting in fuse blowouts.​Poor heat dissipation: Enclosed installation of the module leads to insufficient heat dissipation, acceler
Dedicated Vacuum Contactor Solution for Port Shore Power Systems
I. Background and Challenges​Shore power systems have become core technical equipment for ports to reduce carbon emissions and noise pollution. However, these systems face two major challenges in the harsh operational environment of ports:​Severe Environmental Corrosion: High humidity and salt spray in port areas cause serious corrosion to metal components and enclosures of electrical equipment, significantly impacting electrical lifespan and operational reliability.​High Switching Requirements:
Vacuum Contactor Industrial Power Control Solutions
Application Background and Pain Point Analysis​In modern industrial manufacturing power control systems, traditional contactors exhibit significant limitations under specific operating conditions:• ​Frequent Start-Stop Operations: Traditional contactors have limited mechanical lifespan, with frequent operations leading to coil burnout and mechanical jamming.• ​Poor Adaptability to Harsh Environments: Contacts are prone to oxidation in dusty environments, resulting in increased contact
