What is the Composite Hollow Insulator?
The Composite Hollow Insulator is one of the critical apparatuses utilized in high-voltage electrical structures because of its exceptional electrical insulation and mechanical strength. This insulator comprises two main parts: An inner insulation core and an outer protective layer to finish the design look of the cable. The core of the composite structure comes with fiberglass reinforced plastic (FRP) so that the structure can have solid mechanical integrity and high environmental durability with issues like corrosion and degradation. FRP is much lighter in weight than porcelain insulators and hence can be handled and installed with much ease. The external sheath is produced by silicone rubber that has incredible pharmacoresistance and hydrophobicity. This assists in shedding water and avoiding surface flashovers especially during wet weather to guarantee performance is not compromised. Silicone rubber also offers protection from UV radiation, ozone, and other environmental factors, which in turn increases the life of the insulator. It combines the advantages of FRP and silicone rubber where the final product is lightweight, but also very durable against mechanical shocks and other forms of environmental stresses. Wishpower is one of the leading Global hollow insulator manufacturers serving your company with top-quality products and services.
Why choose Wishpower’s hollow core insulator?
- Reliability and life:
Wishpower’s hollow core insulator employs high-quality glass fiber reinforced plastic (FRP) for the insulation and has silicone rubber skin outside the insulation. The above-said combination is well suited for usage in rough conditions like high-temperature usage, low-temperature usage, high humidity, and pollution and exhibits very good anti-aging properties and can have a very long life which in turn guarantees long-term stability of the product.
- Mechanical strength and seismic performance: Mechanical strength and seismic performance:
In terms of tensile strength, bending strength, and impact resistance, our products have passed the test and can resist external force shock and vibration in the earthquake zone and high wind speed zone. These insulators have the best mechanical attributes for safety and reliability under such conditions.
- Electrical performance:
The insulators have good electrical features, concerning power frequency withstand voltage, lightning impulse withstand voltage and pollution flash withstands voltage. These performance indicators have been stiffly tested and checked to enable the insulators to stand in high-voltage environments with good insulation features and efficiency.
- Installation and maintenance:
Our products are designed with the following specifications: Elegant and sleek in Appearance, Lightweight and easy to handle, and Quick and easy to install as they cut construction time and difficulty. They possess good inherent cleaning and anti-stain properties, which help in the reduction of workload in daily usage, increase construction speed and safety, and decrease operating expenses.
- Materials and manufacturing process:
As for the source of materials, materials are strictly controlled, the materials are from domestic reputable first-tier suppliers while insulation materials used are the products developed by our company and we strictly control the quality of them during the production process. The continued application of new production technology makes the insulators of high quality and stable in the market making our insulators competitive in the market.
- Cost-effectiveness:
The products we offer are cost-efficient, affordable first-time purchases and with installation and maintenance costs, long-lasting. The resource usage is optimal, which decreases costs and contributes to the non-reckless spending of the funds assigned to the project.
- Standards and certifications:
All our products follow international and domestic standards including; IEC technical specifications, ANSI technical specifications, and the State Grid specifications. The product has been rigorously certified and tested either by third parties and all the customers can be assured of the products they are buying.
- Supply chain and delivery time:
We have established a stable supply chain management system to ensure that products can be delivered on time to meet the project schedule requirements.
- Environmental protection and safety:
We pay much attention to the environmental protection and safety factors; the influence of the product production process on the environment is small and no toxic component is emitted during the use of products. During its usage and maintenance, the health of construction workers and the public who interact with the final product is fully protected and the product complies with the environmental/basic safety standards.
Application
- High-Voltage Transmission Lines:
They are used in overhead, electrical power transmission schemes to suspend and also to isolate the electrical conductor. They are very essential in ensuring that there is reliability and security of electricity transfer over large distances.
- Substations:
These insulators are applied in substations in various apparatus for instance transformers, circuit breakers, and switch gears. They are expressed to offer vital measures of protection and support, which make high-capacity equipment run reliably.
- Railway Electrification Systems:
They are employed with railway electrification that insulates and supports overhead contact lines that supply power to electric trains.
- HVDC (High Voltage Direct Current) Systems:
Within HVDC systems, they serve to support and electrically isolate the high voltage direct current lines and apparatus to enable efficient electricity transfer over long spans only.
- Wind and Solar Power Installations:
They are employed in wind and solar power to provide insulation as well as mechanical support for power generation and distribution system’s electrical parts and connections.
- Urban Power Distribution Networks:
Those insulators are applied to insulate and support overhead and underground electrical power supply systems in cities.
- Industrial Applications:
Hollow core composite insulators are applied to insulate and support high-voltage equipment and coupling in industrial establishments like factories and plants.
