Adhering to “Three Global Goals, Three Firsts,” ZTT leverages leading technology, reliable services, and efficient delivery to create holistic value for clients worldwide.

Technical Highlights

Our technical highlights stem from deep multi-domain practice and sustained R&D, and are manifested as verifiable, industry-leading advantages.

Independently Developed Fiber Optic Communication Supply Chain—Collaborative Innovation and Deep Customization Across the Entire Chain

Vertical Integration Capability

From optical fiber preforms, optical fibers, and optical cables to optical communication equipment, we have mastered the core technologies across the entire industry chain. This enables us to provide customers with end-to-end optimal solutions, not just a simple assembly of products.

Key Technological Breakthroughs

We maintain a leading position in areas such as ultra-low loss optical fiber, multimode optical fiber, and specialty optical cables. Our products are widely applied in high-end scenarios including 5G backbone networks, data centers, and marine observation systems.

Customized R&D

Leveraging the advantages of our full industry chain, we can quickly respond to customers’ specific needs, providing deep customization services from materials to finished products to address industry pain points.

Specialized Submarine Cable Manufacturing Capability—Exceptional Performance and Reliability in Extreme Environments

“Deep, Far, High” Technological Barriers

Our submarine optical cables and power cables are engineered to withstand extreme environmental challenges such as ultra-deep-sea pressure, long-distance transmission, and strong electromagnetic interference.

System Solutions

We provide not only cables but also a complete submarine communication/power transmission system, including repeaters and branching units, with leading technological complexity and integration.

Technology Spillover Effect

The high-reliability and high-durability technical standards accumulated in the marine field are applied to land-based high-voltage and ultra-high-voltage cable products, ensuring ultimate safety for all energy network projects.

Global Leader in Power Transmission Products and Services — Integrated Technologies for Smart Grid and New Energy Integration

Green Energy Connection Expert

In the field of new energy such as photovoltaic and wind power, we provide a full range of cables and connection solutions from the power generation side to the grid side. We are particularly leading in ultra-large cross-section and ultra-high-voltage direct current transmission technology, supporting the national “Dual Carbon” goals.

Smart Grid Technology

Our products such as OPGW and smart distribution network cables integrate power transmission and condition monitoring functions, providing foundational support for the digitalization and intelligentization of the power grid.

After-sales Service

Synchronized with our global footprint, we deliver rapid response and lifelong care, ensuring exceptional service reaches every corner of need.

Preventive
Maintenance

Based on a deep understanding of product performance, we proactively offer customers preventive maintenance plans and solutions, shifting from “reactive repair” to “proactive maintenance” to minimise operational risks to the greatest extent.

Logistics Service

Our powerful global logistics capability serves as the strong backbone of efficient delivery, ensuring every product we ship reaches customers on time and in perfect condition.

Customised Transport Solutions

We design professional logistics plans tailored to different types of products (such as super-large spools, transformers, energy storage cabinets), integrating multiple transportation modes including specialised vehicles, railway, and air freight.

Heavy-Lift & OOG Logistics Expertise

In sectors such as marine and power, we possess extensive experience and professional capability in handling extra-long, overweight, and oversized cargo, ensuring safe and precise door-to-door delivery.

Emergency Logistics Channel

For urgent orders or spare parts critically needed at project sites, we activate a green emergency logistics channel, prioritising resource allocation to ensure delivery in the shortest possible time and safeguard our customers’ project schedules.

Local Spare Parts Inventory

We establish spare parts warehouses in key market regions to ensure that in the event of an unexpected failure, replacement products can be provided immediately, minimising customer downtime losses as much as possible.
