Project Overview

A government-led power grid renovation project was launched in the capital city of an Asian country to upgrade the reliability and safety of the urban electricity distribution network.

The project serves nearly 800,000 electricity users and operates more than 7,300 km of transmission and distribution lines. With an annual electricity distribution volume of approximately 3.7 billion kWh, the local government has continuously invested in modernizing its electrical infrastructure.

In 2024 alone, over USD 160 million was invested in grid upgrades to improve power distribution efficiency and ensure long-term system reliability.

To support the power grid modernization, the project required reliable electrical protection devices such as high-performance
Miniature Circuit Breaker and
Molded Case Circuit Breaker.

Customer Needs and Challenges

Customer Needs

The engineering contractor responsible for the grid upgrade required reliable circuit protection equipment to ensure the safe operation of the distribution system.

Key requirements included:

• Reliable overload protection and short circuit protection
• Easy installation and maintenance for distribution panels
• Compliance with local electrical safety regulations
• Long service life suitable for large-scale urban power systems

Customer Challenges

During the supplier selection process, several issues were identified:

• Many suppliers were unable to provide valid certification and professional testing reports.
• Some manufacturers had long delivery times, which could delay the project schedule.
• The contractor required verified testing data to confirm product performance before approval.

These challenges made it difficult for the project team to identify a reliable supplier for circuit protection equipment.

Electrical Protection Solution Provided by EBASEE

To support the power grid renovation project, EBASEE delivered a comprehensive electrical protection solution including:

10kA Miniature Circuit Breakers (MCB)

1600A Molded Case Circuit Breakers (MCCB)

These products were designed to protect both residential distribution boards and main power distribution panels in the upgraded grid system.

Key Advantages of the Solution

• High breaking capacity for reliable short-circuit protection
• Stable overload protection for power distribution circuits
• Durable design suitable for long-term infrastructure projects
• Competitive cost compared with traditional European brands

This solution ensured both technical reliability and cost efficiency for the project.

Product Verification and Testing

To ensure full compliance with the project requirements, EBASEE provided multiple verification steps.

1.International Certification

All products were supported by professional testing reports and certification provided by Intertek, ensuring compliance with international electrical standards.

2.Sample Testing

EBASEE provided free product samples for the customer to perform independent testing before final procurement.

3.Laboratory Verification

Testing processes were recorded in the CNAS-certified laboratory, providing reliable verification data and transparent product evaluation.

These steps significantly increased the customer’s confidence in the product performance.
