Supply Various High Voltage Insulators to Fulfill Your Needs

As your trustworthy epoxy insulator manufacturer, Liyond offers superior tension insulators that apply to various requirements. We provide OEM services for diverse needs. Here are the following indoor insulator you can find at Liyond:

By Construction

Our busbar insulators are mainly made from epoxy resin cast insulators. Our insulators are featured with high strength, excellent corrosion resistance, excellent electrical performance, and high safety performance.

Our post insulators are a kind of HV insulator that are structured based on the APG, GB, and other standards. Liyond post insulator is made from top-notch materials for long-lasting use.

A bushing insulator is a type of hollow electrical insulator that lets an electrical conductor safely go through a conducting barrier without making electrical contact with it.

Capacitive insulator are also known as capacitive voltage detecting insulators which work on the principle of a capacitive voltage divider. Liyond offers durable and high-quality capacitive insulators that will fit your requirements.
We offer conjoined insulators for your electric system or equipment that are characterized by busbar support insulators’ excellent corrosion resistance, high strength, and high safety performance.

By Material

A composite insulator, also known as polymer insulator is a type of material resistant to electron flow due to the low subatomic particle amount. This is extensively used in the electrical and electronics industries.

Epoxy resin insulators are excellent electrical insulators and protect electrical parts from overloading, short-circuiting, accumulating moisture, and dust. Liyond offers a variety of best quality high voltage insulators for your project needs.

You might think copper is only for conduction, but actually, a white copper can be a good insulator. Our white copper insulators secure electrical parts from overloading, short-circuiting, accumulating moisture, and dust.

Applications of Our Insulators
Can be Used

As your top manufacturer in OEM insulator services, Liyond produces high tension insulators with excellent low conductivity and prevents electrical conductors from making unintended contacts. Our capacitive insulators can boost the performance of your system and equipment, because they can increase the pollution flashover voltage, greatly reduce the line maintenance workload and power outage time, and improve the reliability of the power supply.

They are mainly used in power systems of various voltage levels of transmission lines, substations, electrical equipment (electric porcelain water heaters), and other special industries, such as rail transit power systems, to connect conductors or components of different potentials, insulate and support.

Electrical Switchgear

Since electrical insulators can separate the conductors from one another, they require a lot of electrical systems, like in electrical switchgear .


Epoxy insulators are helpful because they ensure the electrical parts do not touch the ground. This is why all substation devices in contact with an energized line or bus employ an insulator.


Transformer insulators are necessary for power transformers because they work as a dielectric by storing electrical charge when the transformer is energized and isolating transformer components that exist at different voltages.


HV Insulators in refinery industries help industrial plants minimize energy costs, which makes chemical processing more efficient. Moreover, insulation safeguards the employees from workplace risks, such as burns and noise pollution.

Power plants

HT insulator in power systems is essential to carry energy transmission line conductors. They are responsible for giving out mechanical support as well as electrical insulation to the conductors.


Insulators like polymer insulators are used in railway industries, whose function is to cushion the passing train's mechanical stress onto the rail and make the rail back to position afterward.

Why Choose High Voltage Insulators from Reliable Insulator Suppliers

It is essential to get your high voltage insulators from most selected suppliers that are capable of providing efficient insulation performance for various power grids. Liyond, a reliable insulator manufacturer, has a comprehensive quality control system and high-end assembly line to ensure on-time deliveries and competitive prices. Here are the features of our indoor insulator:

Enhanced Process Performance

Our capacitive epoxy insulator and sensor boost the electrical performance of your system, equipment, and budget because they reduce emissions and prevent moisture condensation in the device.

Less Mechanical Pressure

Using our electrical standoff insulators offers lesser mechanical pressure on your desired application since they reduce heat transfer by reflecting thermal radiation or decreasing thermal conduction and convection from one object to the other.

Good Support from Conductors

Busbar support insulator is a good shield for electricity and heat due to the good support it provides to the overhead conductors.

Wide Application

Liyond manufactures high-quality polymer insulators and sensors. Our HV insulators are used in substations to protect the switchgear and other insulating media like the function of bushing in the transformer.
