The Solutions For Sourcing Electrical Insulation Rods

The below information will help you to choose rod materials according to your application requirement. You can download the related datasheet here for your reference.

Epoxy Glass Fiber Tube

Wall Thickness: Minimum 0.08″
ID: Minimum Inner Diameter 10mm
OD: Maximum Outer Diameter 800mm

Epoxy fiberglass cloth tube is made of non-alkali fiberglass cloth for electrical purposes impregnated with epoxy resin and phenolic resin under heat and hot pressing with excellent dielectric property and mechanical property, strong mechanical processing property, and good moisture resistance.

Due to its high mechanical properties at medium temperature, epoxy laminate is suitable for the high insulation structure of mechanical, electrical, and electronic components.

Glass Epoxy Filament Wound Tube

Wall Thickness: Minimum 0.08″
ID: Minimum Inner Diameter 10mm
OD: Maximum Outer Diameter 800mm

Glass epoxy filament wound tube is a tube-like laminated product, which is made of fiberglass yarn impregnated with insulating jelly with different resin ratios like epoxy resin, and then rolled, baked, and cured under heat and hot pressing with good dielectric property and mechanical property, and higher thermal resistance property. The insulation class is H class.

Phenolic Cloth Tube

Wall Thickness: Minimum 0.08″
ID: Minimum Inner Diameter 10mm
OD: Maximum Outer Diameter 800mm

Phenolic cotton cloth tube is a tube-like laminated product, which is made of special cotton cloth impregnated with phenolic resin, and then rolled, baked, and cured under heat and hot pressing. It has excellent radial tensile strength, good mechanical strength, and low water absorption. The insulation class is E class.

【New Energy Industry】

Electrical insulation materials are used for preventing arcing in transformers, stabilizers, circuit breakers, etc. They can withstand insulating properties up to a specified electrical breakdown voltage.

In transformers, the dimensional stability and good dielectric features of the electrical insulation are crucial features. High voltage electrical transformers need insulating materials that can withstand high electrical and physical stresses. High-temperature insulation materials are particularly important to protect components from heat damage in the new energy industry


Bulk Production

We have 2 factories and 5 production lines in China mainland and can produce different material types of insulation materials. Production capacity will meet the needs of different customers. If your demand is huge, we can start up 5 production lines to ensure the delivery time.

CNC Machining

We have everything you need to get custom machining parts. Our CNC machine shop that’s extensively equipped to produce your components economically regardless of order quantity. All you have to do now is give us your requirements and parts’ drawings. Our custom CNC machining service to make the part for you.

Packing & Shipping

In order to ensure that the goods are not easily damaged in transit, we use plywood boxes as outer packing. At the same time, our insulation material will be wrapped with a layer of PP film to ensure that the goods will not be affected by moisture. We use wooden cases or pallets with IPPC marks, which fully meet the import requirements.

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.

STEP4: Manufacturing & Testing 15-20 Days

The bulk manufacture will be started according to the confirmed sample. We should prepare related raw materials and finish your order. After the end of production, our special testing department will test this batch of products and issue a quality certificate. Ensure that the quality of each product is up to standard before it leaves the factory. All will be finished in about 15-20 days.

STEP5: Shipping 10-15 Days

We will book the shipping space in advance while packing your order goods. The goods will be sent to the nearest seaport as soon as they are packed well. We know that due to the epidemic, booking shipping space is more difficult than before, and many cargo ships can not reach Chinese ports on time. Now what we do is to try our best to deliver the goods to the port on time, for saving your time.
