sf6 Rental Service for extra high Voltages

high-voltage Service advantage. The U.S. National Electrical Code or NEC, defines high voltage as any voltage over 600V. High voltage can be AC (alternating current - usually sinusoidally varying) or DC (direct current - a fixed and steady positive or negative voltage) or pulsed (a non-periodic positive or negative pulse of voltage).
