PowerGuard® AL 35kV 100% TR-XLPE CN XLPE UL Type MV-105 Electrical Properties (FLAT TOUCHING)

NOTES

Conductor ampacities are based on the following:

• Load factor of 100% or 75%

• Earth thermal resistivity of 0.900ºC-m/W

• Ambient earth temperature of 20ºC

• Maximum conductor operating temperature of 105ºC

• Concentric neutral wires grounded at both ends (shield circulating currents flowing)

• Minimum separation of 3 m or 9.8 ft from any other underground electrical system or heat source

• Maximum load variation between phases of 10%

• Maximum 910 mm or 36 in depth of burial

• Cable arrangements:

○ Trefoil and touching

○ Flat and touching

○ Flat and spaced 190 mm or 7.5 in, center-to-center

• The ampacity values calculated may be limited by the maximum earth interface temperature due to soil moisture migration or dry out, and has not been considered here.
