IEC® Porcelain Post InsulatorsInsulators for AC and DC Applications
1
For more than a century, utilities have relied on GE to deliver electrical products and services to meet their reliability and operational performance needs. GE is a leading provider of transmission and distribution solutions as well as grid automation systems that maximize a utilities operational efficiencies and provides their customers’ with reliable power.
Overview
Through an alliance with XD Electric, GE has extended its portfolio to include high and ultra high-voltage power equipment, supporting the highest transmission voltage levels in the world. XD Electric is one of China's largest high voltage equipment manufacturers dedicated to the research, application and development of critical transmission equipment and solutions. XD Electric has a broad range of products to transform and direct the flow of power for industrial, commercial and residential users. The XD|GE partnership brings end-to-end transmission solutions to meet the growing global demand for electricity. The combined portfolios of GE and XD provide a comprehensive range of technology solutions to address the unique challenges faced by the utility sector and energy intensive industries.
XDlGE IEC Post InsulatorsXD|GE provides a full range of porcelain and polymer housed IEC rated insulators for AC and DC transmission, substation, and distribution applications. In most cases, one of our standard product offerings will meet your application needs. However, if your requirements do not match one of our standard products, we will work to provide the product you need for your application.
XD|GE solid core post insulators are widely used in power plants, transmission substations, distribution substation and high voltage power equipment up to 1100kV. These solid core post insulators are used in applications for both insulating and structural support of live components.
Product Features
• High mechanical strength design of insulators including cantilever, torsion, compression and expansion strength
• Anti-ageing, anti-UV, anti-sandstorm design
• Smooth surface with high hardness and exceptional anti-pollution performance
• Minimal displacement under load
Manufacturing ExcellenceXD|GE produces a variety of insulators in its modern production facilities. The isostatic production processing line is the most advanced insulator production technology, developed in Sweden and adapted by XD|GE to attain the highest performance.
In order to guarantee the electrical and mechanical properties, all insulators are individually examined by an ultrasonic detector and a four-directional cantilever stress test.
QualityQuality is critical for XD|GE and this focus is evident throughout our manufacturing environment. Quality begins with an incoming inspection of all purchased and outsourced materials to ensure that before we begin the manufacturing process, we have the best possible inputs. Each production facility maintains working environment standards including controls of cleanliness, temperature and humidity.
Through production and assembly, there are multiple checkpoints for critical process steps, including both visual inspection as well as stopped flow inspection performed to documented test plans. Our production facilities follow a strict non-conforming procedure to identify and control and to avoid the use and delivery of the non-conformity.
In addition, XD|GE has a dedicated measuring and inspection department with certified, full-time inspectors in each of our manufacturing sites. This department provides a secondary cross-inspection for work in process and finished products, ensuring quality is achieved throughout the manufacturing process. First pass yield and cost of quality data is maintained and analyzed per product family.
