Electricity distribution companies from more than 40 countries worldwide already made the decision to trust the knowledge and technology of our company.

Our company was also an exhibitor this year at the world’s largest energy fair in Hanover. Most contain our own built-in innovative patented solutions.

In the company, we are aware that such fairs represent the beginning of concluding new deals on foreign markets, which is also our main goal. Our showroom A41 was in Hall The fair also presents an opportunity to deepen existing contacts.

This second edition cancels and replaces the first edition published in Shopping Cart Your shopping cart is empty. Independent laboratory tests have verified the superiority of silicone rubber in terms of hydrophobicity, resistance to UV and surface tracking performance in contaminated environments, chemical inertness, temperature stability and other key insulating properties.

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. This edition constitutes a technical revision. The advantages of polymer housed arresters — reduced size and weight, and enhanced safety — have been refined in this new generation of surge arresters: Privacy Terms of Use Sitemap.

New Edition of IEC Published | In Compliance Magazine

Surge arresters – Part 8: Accessories for overhead networks We produce different patented accessories for MV power lines. This edition includes ice following significant technical changes with respect to the previous edition: Give feedback about the content of this standard. Check video at https: In addition, long term environmental testing has verified the lifetime superiority of UltraSIL silicone rubber when compared to other polymeric insulating materials.


This document defines surge arresters to protect the insulator assembly from lightning-caused over-voltages only. Full text browsing 6009 To ensure that the arrester’s capabilities will not be exceeded, the resources of the Thomas A.

The UltraSIL housed surge arrester incorporates the industry recognized superior polymeric material — silicone rubber. 60099 ground lead disconnector is optionally available for use on systems having 20A or more of available fault current. In our production is already for 9 months fully implemented the collaborative robot UR5 from the Danish company Universal Robots.

Consider the permissible magnitude and duration of these overvoltages including the full time of system back-up protectionwith appropriate allowances for any recent arrester discharge energies. We are particularly pleased by the visit of this fair because we carried idc some business 06099 with potential customers with whom we met at the Hanover Messe fair in previous years.

The number of visitors and established business contacts is in line with expectations. Iwc the public tender “Incentives for research and development projects 2” we received grants for “Development of a system for monitoring the functionality of surge arresters”. After production, every MOV disk must pass a series of electrical tests designed to ensure the highest individual disk quality. Your shopping cart is empty.

The fair fulfilled our expectations. Under some special system conditions, such as transformer energization using certain types of connections and ferroresonance, higher voltages can be experienced by the arrester.

Therefore, and since metal-oxide resistors are not permanently connected to 660099 line, the 600099 items are not considered for this document: Consult with your Cooper representative to have your individual system application needs studied. These MOV disks have proven their reliability and protective abilities through years of in-service use. The second application criterion to be met is a condition established by the effectiveness of system grounding.

The voltage withstand capability application on ungrounded systems is 1. LV surge arresters They have IP67 protection which ensures reliable operation in all environments. This website uses cookies to ensure you get the best experience on our website. PKI – post insulators They have an innovative insulating head with integrated conductor clamping system.

The fair was held from 23 to 27 April The Lightning discharge capability test has been completely re-written and irc to Test to verify the repetitive charge transfer rating, Qrs with lightning discharges to reflect changes introduced in IEC Ed.

NKI – tension insulators Our tension insulators have specified mechanical load 90 kN. Power-Frequency Overvoltages The second application criterion to be met is a condition established by the effectiveness of system grounding. Edison Technical Center and their systems application engineers are available to make recommendations.

6099 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 most important products are low and medium voltage surge arresters and medium voltage insulators.

Metal-oxide surge arresters with external series iiec EGLA for overhead transmission and distribution lines of a.

Email or password incorrect. In addition to testing to evaluate the performance of the MO resistors, procedures for evaluating the performance of the EGLA series gaps have been introduced. Gapless surge arresters must be selected with sufficient steady-state self impedance to withstand the application of line-to-earth power frequency voltages under all system conditions of operation.

The disconnector will sense and disconnect the ground terminal in the unlikely event of arrester failure, preventing a permanent system short circuit.

Using Metal Oxide Varistors MOVs having excellent electrical properties, these arresters provide superior overvoltage protection for MV distribution systems.
