What is the FiberGlass Tube?

Fiberglass Tube is a structural fiberglass, i.e., fiberglass composite material part in cylindrical form. Glass and fiber composite materials combine the strength and durability of glass with the lightweight and forms flexibility of fiber composite materials in this tube. This device is intended to be outstanding in mechanical strength, electrical insulation, and corrosion resistance and works perfectly in industrial applications. Used in harsh conditions environments like high temperatures, moisture, and chemical exposure, they are widely used. They offer good dimensional stability and can withstand mechanical stress, and so are very good materials for supporting electrical components, for shielding electrical components, and to protect electrical cables or wires. The diameters, lengths, and resin compositions of the tubes are tailored for specific applications, such as varied operational requirements.

 

Types

1. Fiberglass Wound Tube

It is a tube made from continuous glass fiber wound on a mandrel; the fibers may be combined with a resin to hold them together. Customization in terms of thickness, strength, and flexibility is done by varying the number of layers and the fiber orientation undertaken during a winding process. In most high-strength applications such as electrical insulation, industrial machinery, and structural components, these tubes are required to resist impacts and are durable.

2. Fiberglass Pultruded Tube

Continuous sheet fiberglass compounds are pulled through a resin bath and then through a heated die to form the tube by pultrusion. The consequence of this is that it forms a continuous, uniform tube of consistent mechanical properties and precise dimensions. The lightweight and strong pultruded tubes are known for electrical insulation, structural reinforcements, and protective casings in harsh.

3. Fiberglass Extruded Tube

In the glass fiber manufacturing process, glass fibers are made by mixing with resin and driven through a material die to produce a tube. With this technique, continuous tubes with uniform cross sections and equal wall thickness are obtained. For applications that need high dimensional accuracy and uniformity, extruded fiberglass tubes are often used (typically for cables, electrical insulation, and aerospace components).

4. Fiberglass Molding Tube

In the molding processes, fiberglass strands, chopped in one form or another, are combined with resin and are placed in a mold, subjected to heat and pressure to form the tube. It enables the making of complex shapes and custom designs. Applications using these tubes include automotive parts, electrical insulators, and structural components, as well as other applications requiring specific shapes, high strength, and electrical insulation.

5. FiberGlass Resin-Impregnated Tube

Resin is impregnated Fiberglass filaments and wound or molded into tube shapes. When the resin dries, the tube is strong, tough, and resistant to weather.   Applications using this type are commonly found in electrical components, high voltage cable insulation, structural parts that must be protected from moisture and chemicals, and chemical tanks and other vessels.

 

Application

1. High-Voltage Insulation:

Fiberglass tubes are used as insulation components of transmission lines and substations due to their excellent dielectric properties and mechanical strength, therefore it allows safe and efficient power flow.

2. Transformer Bushings:

They can perform structural and insulation tasks in transformers with good resistance to electrical stress and environmental aging.

3. Circuit Breakers:

Used as insulating sleeves and support structures to protect live parts to safely break the electrical current.

4. Busbar Supports:

Fiberglass tubes are used to insulate and support busbars in power distribution systems with mechanical stability and electrical insulation under high current loads.

5. Lightning Arresters:

They are incorporated in the construction of lightning arrester components where they serve as protective insulation to high voltage surges and environmental stresses.

6. Cable Protection and Insulation:

Fiberglass tubes are used as conduits or protective sleeves for electrical cables providing excellent thermal and electrical insulation, protecting power cables from accidental disconnection due to harsh physical conditions.

7. Switchgear Components:

They are used in switchgear assemblies to provide insulation barriers, spacers, and support structures, and are used to ensure operation reliability in high-voltage environments.

8. Pole-Mounted Equipment Supports:

Lightweight and durable support structures for pole-mounted transformers, switches, and insulators in overhead distribution systems.
