Key features

Superior Pollution Resistance: 2-2.5 times higher wet withstand voltage than porcelain, ideal for coastal/industrial areas.

Lightweight & Compact Design: 1/6 to 1/19 the weight of porcelain, ensuring effortless transportation and installation.

Maintenance-Free Operation: Hydrophobic silicone rubber sheds eliminate need for cleaning or routine insulation monitoring.

High Mechanical Strength: Epoxy fiberglass core offers 8-10x strength of porcelain, resisting shock, vibration, and deformation.

Customizable Specifications: Rated voltage (10kV-1100kV) and physical dimensions can be tailored to specific project needs.

Robust Environmental Sealing: Hermetic sealing (IP68 optional) prevents moisture ingress and ensures long-term insulation integrity.

International Certifications: Compliant with IEC, ANSI, and GB standards; holds ISO 9001, ISO 14001, and CE certifications.

AI-Powered supplier vetting

SummaryThe supplier is a limited company with five employees and a valid import/export license. It reports an annual production capacity of 60,000 tons and cooperation with Chinese national and local power grids, but the provided information does not independently verify these claims. The supplier offers sample, design, full, and minor customization, provides ODM services, and reports new product activity during the past year, with one R&D engineer identified. Service limitations include no overseas agents or branches, overseas warehouses, overseas showroom, inventory capability, or offline trade-show participation. Financial records are indicated for 2021–2023, but no financial figures or assessment results are provided. No formal certification, after-sales capability, or specific customer cases are documented.

Supplier typeThe supplier is legally identified as a limited company, not part of a larger company group, with five employees and a valid import/export license. Its stated business scopes cover mechanical equipment, wind turbines and components, rail-transit systems, environmental equipment, underwater systems, hardware, and other products, indicating a diversified trading and industrial-equipment profile.

R&D capabilityThe supplier reports new products during the past year, identifies one R&D engineer, and provides ODM services. However, it has no available SDK, and no R&D spending, patents, laboratory resources, or documented innovation results are supplied; the evidence supports some innovation activity but not a broad or strongly validated capability.

Production capacityThe supplier states annual production capacity of 60,000 tons and the ability to produce multiple product lines simultaneously while shortening production cycles. It reports one-month average lead times in both peak and off-season, but no inventory capability, no confirmed manufacturing-capacity contract, and no detailed product-specific tonnage are provided.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, and minor customization. It also reports ODM service availability, providing direct evidence of broad product-design and customization support.

Client casesThe supplier states that it is one of the cooperating manufacturers for the Chinese National Power Grid and local power grids. This is a stated customer-related reference, but no customer names, contracts, project details, order scope, or independent verification are provided; no other specific customer cases are documented.

Product Q&A

Q:What is a post insulator?

A high-voltage insulator used to support conductors in substations and power lines, made of composite materials for better performance.

Q:Why choose composite post insulators?

They're lighter, stronger, and more pollution-resistant than porcelain/glass, with minimal maintenance.

Q:How does silicone rubber help?

It repels water, resists UV/chemical damage, and prevents flashovers in wet/polluted areas.

Q:Do they need maintenance?

No. Unlike porcelain, they don't require cleaning or insulation tests.

Q:What packaging and shipping methods do you offer?

Each Isolation Switch is packed in sturdy, export-grade wooden crates to prevent damage during sea freight. We provide reliable international shipping with full tracking information.
