Description
The X-Type series comprises medium- and high-voltage brushless synchronous generators, designed and manufactured at the plant in Montecchio Maggiore (Vicenza province, Italy). The series includes four four-pole frame sizes at 1500/1800 rpm: ECO43 — 800–1,300 kVA (shaft height 400 mm), ECO46 — 1,300–2,500 kVA (500 mm), ECO47 — 2,500–4,000 kVA (560 mm) and ECO49 — 4,000–5,000 kVA (630 mm). Rated data are given for 50 Hz, class H, 40 °C and cos φ 0.8 at 11 kV. Medium-voltage versions are produced up to 7.2 kV, high-voltage versions up to 13.8 kV. The basis of the series’ reliability is the class H+ HVi insulation system, developed jointly with Von Roll: low-viscosity class H epoxy resin without release of volatile organic compounds, mica tapes and mechanical protection with glass fabric, and vacuum-pressure impregnation (VPI). The insulation is designed for voltages up to 15.75 kV. In tests to IEC 60034-18-31 and IEEE 1776, which lasted 18 months in Von Roll laboratories, the thermal index of the system was 191.8 °C against 180 °C for class H; the manufacturer estimates the service life at continuous class H operation at more than 50,000 hours and gives a 4-year warranty on the medium- and high-voltage parts. The system complies with the REACH regulation, is approved by API for contaminated environments, and is the basis of the PROTEXPLUS protection system. Design: reinforced bedplate, enlarged terminal boxes with a separate zone for low-voltage connections, six leads, windings with 5/6 or 2/3 pitch. Standard protection IP23, on request up to IP45 (ECO49 — IP23), and with air–air or air–water heat exchangers up to IP56; cooling IC01. Single-bearing version with SAE 1/0/00 flanges and SAE 14/18/21 disc couplings, or two-bearing B3B14. A digital DER2 regulator with a high-dynamics module is fitted as standard; DECS-150 or DECS-250 on request. Options: bearing and winding temperature sensors, vibration sensors, anti-condensation heaters, current transformers, ball, roller, insulated or sliding bearings, excitation from an auxiliary winding or PMG, over-excitation protection. Applications: generator sets feeding a 3.3–13.8 kV network, cogeneration, oil and gas and marine facilities, heavy industry, data centres. The factory test stand permits acceptance tests in the presence of the customer. High-voltage generators are UL listed.
