    Copper conductors

    Hello all I need an insulated multistranded copper conductor which can carry 8-9 Amp current, should be screened, having an insulation which can withstand working voltage of 1.5KVrms. Moreover insulation should be flexability as this cable is needed to be wind/unwind regularly. As for as...

    E/O Media Converter

    Hello all I am using two Blackbox media convertors in a pair (Ethernet to optical and vice versa) in order to send 100Mbps ethernet (TCP/IP) data on single mode (SM) optical fibre pair using 1310 wavelengths. The specifications of media converter says that ethernet data can be sent over 10Km SM...

    High Voltage (2 Kvrms) shielded cables

    Hello all I need to select/source suitable shielded conductor/cable (of 200m lenght) for carrying 2 KVrms sinewave signal of 2 KHz frequency. The current will not exceede from 1.5 amp. Moreover 2 to 4 conductor pairs will be placed side by side so individual conductor's shielding required for...

    impedance matching transformer

    Hi all I have a QSC  audio amplifier (RMX 4050HD) and an acoustic transducer having input impedance of approx 180 oham at resonant frequency. QSC amplifier can provide about 2000 watt to 2 oham load (speaker) . If i directly connect transducer to amplifier, i only get 50-60 watt output. I...
