The insulated fiber tube Complete FAQ Guide

In the power industry, choosing the right insulating pipe is critical. We need to first understand the properties, uses and differences between insulating tubes made of various raw materials (e.g. fiberglass, GPO-3, epoxy resin, phenolic cloth, kraft paper) are crucial for insulation protection of electric motors, transformers and other equipment. The purpose of this article is to provide a comprehensive guide for purchasers in the transformer, motor, and power industries to help them gain an in-depth understanding of the various insulating tube materials so they can make an informed choice.

1. Fiberglass Tubing
Characteristics : With excellent mechanical strength and heat resistance, it is one of the common insulating pipe materials.
Uses : Suitable for applications requiring high strength and corrosion resistance, such as motor insulation and electrical equipment insulation.

2. GPO-3 Pipe
Characteristics : GPO-3 is an epoxy resin reinforced phenolic paper adhesive material with excellent electrical insulation properties and heat resistance.
– Uses : Widely used in electric equipment, switchgear and other fields, especially suitable for occasions requiring high temperature and electrical resistance.

3. Epoxy fiber tube:
Characteristics: With excellent chemical resistance and mechanical strength, it is a common insulating material.
– Uses : Suitable for electrical equipment requiring good corrosion resistance and mechanical protection.

4. Phenolic Cloth (Phenolic Cloth tube):
– Characteristics: Phenolic Cloth has good mechanical properties and electrical insulation properties, suitable for high temperature environment.
Uses: Commonly used in the need for heat and impact resistance equipment insulation, such as motor coil wrapping.

5. kraft paper (Kraft Paper):
– Characteristics: Kraft paper has excellent insulating properties and mechanical strength, is a common insulating material.
– Uses : Widely used in transformers, insulating mats and other electrical equipment, to provide reliable insulation protection for the circuit.

Consider the use : According to the working environment and working temperature of the equipment to choose the right insulating pipe material.
– Voltage Resistance Requirements Select the appropriate insulating material according to the voltage and current strength to be withstood.
Material durability : Select the material that meets the durability requirements, taking into account the required life span of the pipe and the operating environment.

1. Customization : Original paper and color made from cotton pulp.
2. Chemical treatment:
Impregnation or soaking of cellulose pulp in a solution containing a catalyst, usually zinc chloride, to initiate the vulcanization process.

3. board molding:
-The impregnated pulp is made into flat sheets using a papermaking process, similar to the production of vulcanized fiberboard. The thickness and size of the sheet depends on the desired size of the final tube.

4. roll forming :
-Once the flat sheets are dried, they are rolled around mandrels or cylinders to form them into tubes. The diameter of the mandrel determines the inner diameter of the tube.

5. Pressing and vulcanizing: After measuring the wall thickness according to the heat shrinkage ratio
The rolled pipe is heated and pressurized several times to bond the layers of vulcanized fibers together and complete the vulcanization process. This step ensures that the pipe maintains its shape and structural integrity.

6. Trimming and finishing:
After vulcanization, the end of the pipe can be trimmed to the desired length using a cutting tool.
-The pipe may be subjected to additional finishing processes such as sanding, coating or calendering to obtain the desired surface finish and properties.

7. Quality Control:
Quality control measures are implemented throughout the manufacturing process to ensure that the pipe conforms to the required specifications in terms of size, thickness, strength and other properties.

8. Packaging:
Once the vulcanized fiber pipe is completed and inspected, it will be packaged and ready for distribution to customers
