UltraSIL silicone rubber will not support biological growth algae and mildew and is non-flammable. 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.

Edison Technical Center and their systems application engineers are available to make recommendations. Accessories for overhead networks We produce different patented accessories for MV power lines. To ensure that the arrester’s capabilities will not be exceeded, the resources of the Thomas A. 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.

The rating of an arrester is the maximum power frequency line-to-ground voltage at which the arrester is designed to pass the IEC operating duty test. The fair was held from 23 to 27 April Consult with your Cooper representative to have your individual system application needs studied.

Email or password incorrect. Also, such a fair allows us to understand and analyze the competition. Our most important products are low and medium voltage surge arresters and medium voltage insulators.

LV surge arresters They have IP67 protection which ensures reliable operation in all environments. A disconnector that has operated gives a visual indication of internal arrester damage and the need for arrester replacement.

Surge Arresters 5 kA and 10 kA Class 1 IEC for MV Systems to 36 kV

Most contain our own built-in innovative patented solutions. The disconnector will sense and disconnect the ground terminal in the unlikely event of arrester failure, preventing a permanent system short circuit. Electricity distribution companies from 600099 than 40 countries worldwide already made the decision to trust the knowledge and technology of our company.

Using Metal Oxide Varistors MOVs having excellent electrical properties, these arresters provide superior overvoltage protection for MV distribution systems. 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 number of visitors and established business contacts is in line with expectations. Manufacturing our own MOV disks allows strict quality control over the manufacturing process from start to finish. 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.

A ground lead disconnector is optionally available for use on systems having 20A or more of available fault current. The motive for the participation in the Hanover fair was to establish new contacts with oec partners or representatives of companies that market equipment for power systems.

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.

The second application criterion to be met is a condition established by the effectiveness of system grounding. Power-Frequency Overvoltages The second application criterion to be met is a condition established by the effectiveness of system grounding. Our showroom A41 was in Hall uec This website uses cookies to ensure you get the best experience on our website.

One must pay particular attention to systems having low coefficients of grounding, ungrounded systems and uec that are resonant grounded or that may become ungrounded under abnormal conditions of operation.

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”.

660099 our production is already for 9 months fully implemented the collaborative robot UR5 from the Danish company Universal Robots. PKI – post insulators They have an innovative insulating head with integrated conductor clamping system. 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 600999 out some business talks with potential customers with whom we met at the Hanover Messe fair in previous years.
