ZMS Cables, as a professional and experienced cable company, specializes in manufacturing custom cables of various types.

For medium voltage cables, we have standard medium voltage underground transmission lines consisting of single-core and three-core cables with copper or aluminum conductors.

This includes sheath properties such as polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), polyethylene (PE), ethylene propylene rubber (EPR), and low smoke zero halogens (LSZH).

We also provide expert cable safety performance and installation requirements to ensure legal compliance and your safe use of the cable.

PRODUCT APPLICATION

Medium voltage cables are used in a wide variety of industrial and commercial applications.

In industrial environments, medium voltage power cables are mainly used in power distribution systems.

They can be installed in ducts or conduits and are suitable for both wet and dry locations.

Typical applications include pulp and paper mills, petrochemical plants, water treatment plants, environmental protection systems, and railroads.

Due to their robustness and high electrical stability, medium voltage cables are well-suited for use in harsh environments.

However, the use of medium voltage cables in these applications requires that the cables be rated for maximum tensile strength to ensure that they can withstand the harshest environments.

WARM TIPS

If you don't know how to choose the right cable product, or if you don't find the type and size of cable you need on this page.
Don't worry, please contact us.
You can send us your requirements and we can help you choose the right cable.

You can provide us with the following information: cable voltage, conductor material, insulation and sheath material, shielding type, armor type, etc.
Or you can also provide the cable installation environment, application requirements, etc.
We will serve you wholeheartedly.

How do I choose the right medium voltage cable?

You can choose based on building standards, data measurements, and materials used.

Single-core, two-core, or three-core copper and aluminum cables are most commonly used in daily life.

Product Customization

For your convenience and to extend the life expectancy of your cables, they should be customized to meet your requirements.
Our custom cable solutions can be developed and designed around various parameters that can be changed.
Our medium voltage cables are available in specific and extended lengths to aid in installation and reduce the number of cable connectors.
You can also provide the included cable accessories, and cable sizes are calibrated to match seamlessly.
Your requirements can be realized within the following criteria:

Medium Voltage Cable Testing

Cables are a vital part of safe electricity use.

Our medium voltage cables are guaranteed to follow strict production standards and will also pass the medium voltage cable partial discharge testing.

Packaging

The packaging of ZMS cables is provided in wooden rolls, corrugated cartons, and reels.

The cable ends are sealed with BOPP self-adhesive tape and non-hygroscopic sealing caps to protect the cable ends from moisture.

We can print the required markings on the outside of the drums with waterproof material according to the customer's requirements.

As a professional cable manufacturer, ZMS has a wide range of cable and conductor products for you to choose from.

We will provide attentive service and professional project solutions to everyone who needs them.
