  • Network Switch Tester

    NuStreams P9M - Omnicor

    NuStreams-P9M is a standalone tester for testing residential gateway (IP sharing devices) with 8 LAN and 1 WAN at wirespeed. The compact and lightweight design and built-in tests make it an ideal solution for production test on production line and for analysis and troubleshooting at service centers or maintenance outlets as well.

  • Network Testing and Simulation Tools


    Network IP traffic packet generators are used for network performance testing under maximum or partial throughput conditions. Network health can be analyzed by network traffic measurement in a testbed network, using an IP network traffic generator such as IP Traffic Test and Measure. The traffic generator sends packets, often with a unique packet identifier, making it possible to keep track of the packet delivery in the network. Network impairment simulation (emulation) is a technique for testing the performance of real applications over a virtual network. The aim is to assess performance, predict the impact of change, analyze impairment conditions or otherwise optimize technology decision-making. Measurements usually focus on simulation of conditions like delay, jitter, latency, dropped packets and limited bandwidth.

  • Vacuum Capacitors


    Uses a high vacuum as the dielectric instead of air or other insulating material. This allows for a higher voltage rating than an air dielectric using a smaller total volume.

  • Vacuum Circuit Breakers

    VCB - Omnicor

    A vacuum circuit breaker is a type of circuit breaker where the arc quenching takes place in vacuum. The technology is suitable for mainly medium and high voltage application. developed but not commercially viable. The operation of opening and closing of current carrying contacts and associated arc interruption take place in a vacuum chamber also known as vacuum interrupter. The vacuum interrupter consists of a steel arc chamber in the center symmetrically arranged ceramic insulators. The vacuum pressure inside a vacuum interrupter is normally maintained at 10- 6 bar. Contacts design styles include transverse magnetic field( TMF) and axial magnetic field (AMF).

  • Vacuum Contactor Switches


    Vacuum contactors utilize vacuum interrupter encapsulated contacts to suppress the arc. Such arc suppression allows the contacts to be much smaller and use less space than air-break contacts at higher currents. As the contacts are encapsulated, vacuum contactors are used extensively in rugged environments such as mining. Vacuum contactors are also widely used at medium voltages from 1000-12000 volts, effectively displacing oil-filled circuit breakers in many applications. Vacuum contactors are usually applicable for use in AC systems. The AC arc generated upon opening of the contacts will self-extinguish at the zero-crossing of the current waveform, with the vacuum preventing a re-strike of the arc across the open contacts. Vacuum contactors are therefore very efficient at disrupting the energy of an electric arc and are used when relatively fast switching is required, as the maximum break time is determined by the periodicity of the AC waveform.

  • Vacuum interrupters


    A vacuum interrupter is a switch which uses electrical contacts in a vacuum. It is the core component of medium-voltage and high-voltage circuit-breakers.Since the arc is contained within the interrupter, switchgear using vacuum interrupters can be very compact compared with switchgear using air, SF6 or oil as the arc-suppression medium. Vacuum interrupters can be used for circuit-breakers (VCB), load break switches (LBS), contactors, rail circuit breakers, etc. Circuit breaker vacuum interrupters are primarily used in the power sector in substation and power-generation facilities, and load-switching vacuum interrupters are used for power grid end users.We support national and international standards like ANSI/IEEE C37.60, IEC 62271-100, JIS, GB and GOST.

  • Surge Arresters


    Surge arresters are devices for protection of electrical equipment from over-voltage transients caused by atmospheric or internal switching events. Sometimes called a surge protection devices. They are designed to divert excessive voltages to ground and thus protect equipment in power transmission and distribution systems.Many types of surge arrestors are available in both polymer and ceramic housing and for AC and DC applications. Typically designed to cover voltages from 6.6 kV to 1000 kV arresters protect distribution transformers, power equipment, cables and power station equipment. In special environments metal oxide varistors, also known as zinc oxide (ZnO) blocks, can be used inside GIS housing, pole mounted distribution transformers and power transformers. Prevailing standards governing this type of technology are IEC 60099-4 and IEEE C62.11.

  • Zinc Oxide Blocks


    Zinc oxide (ZnO) blocks for surge arresters have been developed since 1970’. Since then, over 20 million pieces have been delivered all over the world. Backed up with many years of experience, we offer high-quality high-performance blocks in different sizes for light duty to heavy duty equipment and for AC to DC applications, and different installation environments. Typical zinc oxide blocks are available for surge arresters in distribution class, substation class, DC surge arresters class, GIS type surge arresters and oil-immersed type surge arrestors.
