Buyer questions answered before quotation
Can a 110kV project use 132kV equipment?
Only when the utility insulation schedule and highest voltage for equipment explicitly support the selected equipment class.
What must be known before selecting disconnect switches?
Rated voltage and current, short-time withstand current and duration, peak current, insulation levels, operating mechanism and terminal loads.
How are insulator strings matched?
Mechanical load, creepage, coupling, string arrangement, conductor data and tower attachment must be coordinated together.
