STAMFORD HC4/HC5/HC6 — low-voltage synchronous generator 182–1438 kVA
Country: United Kingdom · Model: HC4/HC5/HC6
Low-voltage brushless generators HC4, HC5 and HC6 of 182–1438 kVA. The HC4 gives 204–400 kVA at 50 Hz, the HC5 370–675 kVA, and the HC6 up to 1135 kVA at 50 Hz and 1438 kVA at 60 Hz. These are previous-generation machines that are gradually being replaced by the S-Range.

Description
The HC4 has four poles, up to 500 kVA at 60 Hz, 380–690 V, with the AS440 and self-excitation as standard, and with the DECS150, DM110, MX321, MX341 and MX342 with a PMG sub-exciter as options. The HC5 (up to 843 kVA at 60 Hz) has been discontinued and replaced by the S5. The four-pole HC6 (346–690 V, PMG excitation, MX321) has been replaced by the S6, but the six-pole HC6 is still produced. The winding pitch is 2/3, the insulation is class H and the protection is IP23; for the HC6, IP44 filters are optional, and there are twelve leads with reconnection. Industrial HCI and marine HCM versions are available with different core lengths C–K. The HC5 was built for rail applications for more than 30 years. The generators comply with BS EN 60034, BS5000, VDE 0530, NEMA MG1-32, CSA C22.2-100 and AS1359.
How to choose
The choice starts with the output and the number of poles. The HC4 suits 204–400 kVA, and the HC6 covers 182–1270 kVA and remains the only six-pole machine. For new projects the S-Range is closer, in particular the S4 (210–560 kVA) and the S5 (450–937 kVA), which is exactly what replaced the HC5.
