Ningbo Changshi Boosts OHTL Stringing Solutions to Support Global Grid Modernization

NINGBO, CHINA – The world's power grids are under immense pressure. A combination of aging infrastructure, rising electricity demand from data centers and EVs, and the urgent push for renewable energy is driving a massive, once-in-a-generation upgrade cycle known as "Grid Modernization."

As a leading manufacturer of OHTLstringingequipment.com/Power-Transmission-Line-Stringing-Equipment.html target='_blank'>power line tools, Ningbo Changshi Electric Power Machinery Manufacturing Limited is actively scaling its production and innovation to meet this challenge. Our specialized equipment for overhead transmission line (OHTL) conductor stringing is a critical component in making these modernization projects a success.

The Challenge: Upgrading to Smarter Conductors

Modernizing the grid isn't just about replacing old poles. It's about installing entirely new types of conductors that can carry more power and data. Two key products in this transformation are:

• HTLS (High-Temperature Low-Sag) Conductors: These advanced conductors can transmit significantly more electricity than traditional lines, making them perfect for upgrading existing corridors without building new towers.

• OPGW (Optical Fiber Composite Overhead Ground Wire): This dual-purpose cable provides the grounding protection for the line while simultaneously housing high-speed fiber optics, which are the communication backbone for a "smart" grid.

However, these advanced conductors require specialized handling. They cannot be installed with just any equipment. They demand precision, controlled tension, and high reliability to prevent damage.

Our Solution: The Right Equipment for the Job

This is where Ningbo Changshi excels. Our comprehensive range of hydraulic pullers, Tensioners, and Stringing Blocks is specifically engineered for these modern applications.

• Precision Tension Control: Our hydraulic Tensioners provide smooth, constant tension, which is essential for safely installing sensitive OPGW and HTLS conductors without causing damage to the core or fibers.

• High Reliability: Our equipment is built for demanding field conditions, ensuring that multi-million dollar modernization projects are not delayed by equipment failure.

• One-Stop Supply: We provide the entire package—from the puller and tensioner to the anti-twisting steel wire rope, Conductor Grips, and specialized Stringing Blocks. This simplifies logistics for contractors and ensures full system compatibility.

"The global push for a resilient, modern grid starts with the physical installation. You can't have a 'smart grid' without the lines," said a spokesperson for our sales team. "We are proud to be the trusted partner for contractors around the world, providing the robust tools they need to build the power grid of tomorrow, today."
