INSULATION MATERIALS SOLUTION

Experienced Manufacturer Since 1990

It’s not easy to introduce all aspects of insulation sheets. So we prepare a lot of information here for you to delve into, including types of sheets, general applications, your purchase order process, how we support you, service & advantage, duration estimation, FAQs, and so on. All will guide you to purchase insulation sheets from China.

How To Choose Electrical Insulating Sheets

It is quite essential to know the insulation properties of the materials, including dielectric strength, compressive strength, tensile strength, pressure resistance, impact resistance, corrosion resistance, cryogenic resistance, and flame resistance. The below information will help you to choose sheet materials according to your application requirement. You can download the related datasheet here for your reference.

Epoxy Fiberglass Rod

Epoxy rods are made of high-performance composite materials impregnated in saturated resin solution, heated, cured and Pultruded;

Main features of epoxy rod: insulation, good hardness, low density, good elasticity, corrosion resistance, stable size, excellent mechanical properties, etc

The main application scope of epoxy stick: mechanical equipment, health equipment, leisure sports goods, sporting goods, toys, electrical products, etc

– GENERAL Applications 【Industries We Serve】

Transformers & Reactors

Transformers and reactors both need that insulating materials are flame retardant, heat resistance, weather resistance, high insulation performance, and mechanical strength.

Circuit Breakers

In the molded case circuit breakers, contacts, arc interrupters, release, and operating mechanisms are all installed in a plastic shell through modularization. GPO3 sheet is commonly used as the arc suppression sheet in circuit breakers for protecting.

Rail Transit

In rail transit, there are many modules like motor, traction motor, or interior decoration that will use GPO3, FR4/FR5. It requests the safety performance flame retardant V0 grade, temperature resistance Class F or above, also a certain mechanical strength.

Wind Power Generation

Wind power generation is an important power generation item in new energy. When the fan blades are rotated by the wind, the motor will be driven to generate electricity. FR4 or FR5 materials are mostly used in wind energy motors. It requires temperature resistance above class F and flame retardant V0 level.

Solar Industry

The photovoltaic system is composed of photovoltaic modules, bus boxes, inverter cabinets, distribution cabinets, transformers, and power grids. The insulation requirements are similar to transformer and power grid transmission and distribution. GPO3, FR4, etc. are used insulation sheet materials for supporting, load-bearing, and isolation in inverter cabinets, distribution cabinets, bus cabinets, and switch cabinets.

Industrial Equipment

It has different requirements for insulation materials in the field of industrial equipment. It requires high mechanical performance, environmental protection, easy installation, sealing, etc. in the application of machinery manufacturing equipment, mechatronics equipment, medical equipment, household appliances, central air-conditioning compressors, and other industrial equipment.

The Process Flow & Duration Estimation

Please note that the final cost depends on the customized service you require, the specifications of the raw materials used, the relevant national laws, and the distance of transportation. Take the example of booking a tall container of products:

STEP1: Requirements Communication 1-3 Days

The first step is that we can talk about the thickness, customized size, temperature resistance grade, quantity, and all of your requirements. If you need machining parts, you can provide the drawings, tolerance range, and raw materials requirements to us. Then our engineers will check and reply to your every question so that you can understand clearly about our production planning.

STEP2: Sampling 1-3 Days

For purchasing insulation sheet materials, we will provide 1-2 pieces samples in A4 size for your testing. If you request machining parts, we will process samples according to the confirmed design drawing. Due to the processing difficulty, the time will be different. In general, a4 size sheet samples can be done within 1 day. And machining parts will be within 3 days. Then we will send them to you.

STEP3: Contract & Payment 1 Day

Once the details of the proforma invoice are confirmed by both of us, you can arrange the deposit for us according to the invoice. Meanwhile, we can also provide a Confidentiality Agreement, Quality Assurance Agreement, and International Trade Contract to you. Anyway, you will be safe in doing business with us.

Mr. Heorhii (CEO FROM UKRAINE)WHAT OUR CLIENTS SAY
Looks to be exactly what I was expecting to receive. The external look – absolute 5 stars! Special thanks for the separate protection foil for each sheet – it really made a great job protecting the gloss finish during the transportation – no scratches on the sheets at all. The mechanical properties still need to be checked, but I’m absolutely confident it should be perfect. Also need to highlight suppliers highest communication skills and great support while solving transportation questions. Thanks.
