Electricity distribution companies from more than 6009 countries worldwide already made the decision to trust the knowledge and technology of our company. 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.

Accessories for overhead networks We produce different patented accessories for MV power lines. The second application criterion to be met is a condition established by the effectiveness of isc grounding.

Privacy Terms of Use Sitemap. 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. PKI – post insulators They have an innovative insulating head with integrated 600999 clamping system.

The fair fulfilled our expectations. After production, every Irc disk must pass a series of electrical tests designed to ensure the highest individual disk quality.

This edition includes the following significant technical changes with respect to the previous edition: A ground lead disconnector is optionally available for use on systems having 20A or more of available fault current. 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. The UltraSIL housed surge arrester incorporates the industry recognized superior polymeric material — silicone rubber.

The advantages of polymer housed arresters — reduced size and weight, and enhanced safety — have been refined in this new generation of surge arresters: Also, such a fair allows us to understand and analyze the competition.

The 6009 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.

IEC System of Conformity Assessment Schemes

A disconnector that has operated gives a visual indication of internal arrester damage and the need for arrester replacement. UltraSIL silicone rubber will not support biological growth algae and mildew and is non-flammable. Power-Frequency Overvoltages The second application criterion to be met is a condition established by the effectiveness of system grounding. Table 1 in Catalog Section I provides a general application guide for the selection of the proper arrester rating for a given system voltage and system grounding configuration.

Systems which permit earth faults to remain undetected or operate with one phase earthed for periods in excess of 24 hours will require the use of an arrester having a Uc continuous capability equal to the system maximum phase-to-phase voltage.

In 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”. The fair also presents an opportunity to deepen existing contacts. Most contain our own built-in innovative patented solutions.

6009 Metal Oxide Varistors MOVs having excellent electrical properties, these arresters provide superior overvoltage protection for MV distribution systems. Your shopping 600099 is empty. Designs with the EGLA’s external series gap installed in parallel to an insulator are not covered by this document.

The Lightning discharge capability test has been completely re-written and re-named to Test to verify the repetitive charge transfer rating, Qrs with lightning discharges to reflect changes introduced in IEC Ed.

NKI – tension insulators

LV surge arresters They have IP67 protection which ensures reliable operation in all environments. Metal-oxide surge arresters with external series gap EGLA for overhead transmission and distribution lines of a.

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. The number of visitors and established business contacts is in line with expectations.

Manufacturing our own MOV disks allows strict quality control over the manufacturing ieec from start to finish. Email or password incorrect.

In addition, long term environmental testing has verified the lifetime superiority of UltraSIL silicone rubber when compared to other polymeric insulating materials.

This second edition cancels and replaces the first edition published in
