10kv -110kv Electrolyed Electro-Chemistry Rectifier Transformer Phase-Shift Rectifier Transformers for Metallurgical Industry

[[MetaDescription]]

          FRP test pile is mainly composed of pile body, top cover and other parts. The pile body is generally made of FRP pultrusion profile, which is formed by FRP pultrusion machine at one time and pressed by high temperature, and has the characteristics of hard texture and not easy to deform. The top cover is used to protect the test equipment in the pile body and facilitate wiring and test operation.

          The traditional test pile is made of cement, and its disadvantages are obvious: heavy weight, complex production, high cost, frequent maintenance, inconvenient transportation and installation, etc.Later came the metal test piles, which were significantly lighter in weight but had poor corrosion resistance and insulation when used in outdoor environments.The latest generation is the fiberglass test pile, which perfectly solves the above problems. 

• Product composition:

1. Pile body

2. Top cover

3. Built-in circuit board, wiring terminals and connecting cables

4. Detection hole

5. Surface printing or nameplate

        FRP test pile is mainly composed of pile body, top cover and other parts. The pile body is extruded or moulded by FRP pultrusion machine at one time, which has the characteristics of hard texture and easy deformation. The top cover is used to protect the test equipment in the pile body and facilitate wiring and test operation.

• Use of the product:

        The FRP test pile is different from the ordinary marker pile in the process of use, and the test pile connection line needs to be connected to the pipeline test equipment, so that the device can be connected to the test terminal of the test pile on the surface to detect the corrosion of the pipeline and other problems in the future use.

1. Cathodic protection parameter detection: In the cathodic protection system, FRP test piles are used to monitor the cathodic protection potential of metal facilities such as buried steel pipes to ensure that the pipes are in an effective cathodic protection state to prevent corrosion damage.
2. Pipeline potential and current detection: FRP test piles can also be used to detect the potential and current of the pipeline to assess the operating status and safety of the pipeline.
3. Insulation performance testing: Through specific test methods, FRP test piles can detect the insulation performance of pipelines and find potential leakage or short circuit problems.
4. Warning and protection: FRP test pile also has a certain warning effect, which can remind people to pay attention to the existence of pipelines or cables and other facilities to avoid accidental damage.

          FRP test piles are generally divided into three types: square, round and special-shaped.

        The height of the test pile varies according to the use environment of different projects.
