What is the key role of polymer insulation materials in power systems? This article will give you a detailed answer and provide practical purchase suggestions.
In modern power systems, safety and reliability are paramount. To this end, polymer insulation materials, as an innovative insulation technology, are becoming more and more popular. It not only improves the insulation performance of wires or cables, but also extends the service life of equipment. This article will take you to an in-depth understanding of the core knowledge of polymer insulation materials and their important role in power systems.
Types and characteristics of polymer insulation materials
Polymer insulation materials mainly include the following types:
Linear insulation materials: such as polyethylene (PE) and polyvinyl chloride (PVC), which are widely used in low-voltage transmission systems.
Layer insulation materials: Through multiple layers of alternating different materials, it provides higher mechanical strength and durability, suitable for medium and high voltage cables.
Granular insulation materials: Dispersed in the matrix in the form of microparticles, it enhances the insulation performance of the conductor and is suitable for high voltage environments.
Each type has its unique advantages and scope of application. Choosing the right material can significantly improve the safety of the power system.
Application of polymer insulation materials
Polymer insulation materials are widely used in power systems:
Cable insulation: By wrapping the wire with polymer materials, current leakage and oxidation can be effectively prevented.
Switchgear: Used in disconnectors, circuit breakers and other equipment to ensure electrical safety.
Transformers and booster stations: Provide a reliable insulation layer to prevent electromagnetic interference and dielectric pollution.
How to choose a suitable polymer insulation material?
When selecting polymer insulation materials, the following factors need to be considered comprehensively:
Temperature performance: Select materials with good temperature resistance according to the temperature range of the operating environment.
