Considering the particular design concept and the special application on overhead transmission and distribution lines, some unique requirements and tests are introduced, such as the verification test for coordination between insulator withstand and EGLA protective level, the follow current interrupting test, mechanical load tests, etc.
Our showroom A41 was in Hall LV surge arresters They have IP67 protection which ensures reliable operation in all environments. The motive for the participation in the Hanover fair was to establish new contacts with potential partners or representatives of companies that market equipment for power systems. Valid Estimated date of Estonian translation publication: In addition, long term environmental testing has verified the lifetime superiority of UltraSIL silicone rubber when compared to other polymeric insulating materials.
Most contain our own built-in innovative patented ice. Our company was also an exhibitor this year at the world’s largest energy fair in Hanover.
The fair fulfilled our expectations. Accessories for overhead networks We produce different patented accessories for MV power lines.
A disconnector that has operated gives a visual indication of internal arrester damage and the need for arrester replacement. Surge arresters – Part 8: These MOV disks have proven their reliability and protective abilities through years of in-service use.
The fair also presents an opportunity to deepen existing contacts. The number of visitors and established business contacts is in line with expectations. Learn more about cookies. We are particularly pleased by ie visit of this fair because we carried out some business talks with potential customers with whom we met at the Hanover Messe fair in previous years.
Electricity distribution companies from more than 40 countries worldwide already made the decision to trust the knowledge and technology of our company.
NKI – tension insulators Our tension insulators have specified mechanical load 90 kN. PKI – post insulators They have an innovative insulating head with integrated conductor clamping system.

06099 shopping cart is empty. Give feedback about the content of this standard. The Lightning discharge capability test has been completely re-written idc re-named to Test to verify the repetitive charge transfer rating, Qrs with 6099 discharges to reflect changes introduced in IEC Ed.
Edison Technical Center and their systems application engineers are available to make recommendations. This document defines surge arresters to protect the insulator assembly from lightning-caused over-voltages only. To ensure that the arrester’s capabilities will not be exceeded, the resources of the Thomas A. Shopping Cart Your shopping cart is empty. Designs with the EGLA’s external series gap installed in parallel to an insulator are not covered by this document.
Power-Frequency Overvoltages The second application criterion to be met is a condition established by the effectiveness of system grounding.
Therefore, and since metal-oxide resistors are not permanently connected to the line, the following items are not considered for this document: Gapless surge arresters must be selected with sufficient steady-state self impedance to withstand the application of line-to-earth power 06099 voltages under all system conditions of operation.
