ELECTRICAL
1. All current carrying power cables shall have insulation rated for 90°C operating temperature.
2. The power cables shall be phased and supported to maintain low impedance and assure the mechanical strength necessary
to prevent power cable movement or damage under short circuit currents up to 100,000 RMS symmetrical amps.
3. Power cables shall be of continuous length and be pulled in after the cable bus enclosure is in place. Electrical connectors
shall be used only at the termination of conductor runs or, if necessary, at tap points. Electrical compression
terminal lugs shall be provided by us.
4. The resistance across the enclosure section splice of our Superior Cable Bus shall not exceed 50 μΩ.
5. The Canadian Electrical Code and the National Electrical Code requirement on grounding is adequately met in the design
of the Superior Cable Bus system by the use of high pressure splice joints between bus sections. These splice joints eliminate
the need to use bonding jumpers across cable bus sections. Splice plates and high pressure spline bolts are used to join cable bus sections together.
6. The Superior Cable bus enclosure shall be grounded at sufficient intervals for the purpose of preventing a potential
above ground on the cable bus enclosure in the event of fault.
7. The power cables shall be arranged in a phasing pattern which minimize inter-phase and intra-phase unbalance.
8. Power cable temperature rise calculations and current balance calculations can be provided.
