Overview

This document provides detailed technical specifications, performance ratings, mechanical dimensions, and assembly information for the SLG314 series of electrical windings and generators, specifically focusing on Winding 311 with a 0.8 power factor.

1. Electrical Performance Specifications

Power Ratings

• Rated power is given in KVA and KW for continuous, 125k/40, and 150k/40 duty cycles.
• Voltage ratings cover multiple standard voltages: 208V, 220V, 230V, 240V, 254V, 266V, 277V, 380V, 400V, 415V, 440V, 460V, 480V.
• Power factor is consistently 0.8 across all ratings.
• KW and KVA values are provided for different SLG314 models (C, D, E, EL, F, G) and for 3-phase configurations.

Duty and Temperature Ratings

• Duty cycles include continuous operation and standby ratings at specified temperature rises and ambient temperatures.
• Temperature rise and ambient temperature parameters are indicated but not fully detailed.

2. Mechanical and Dimensional Data

Frame and Flange Dimensions

• Frame diameters and flange sizes are specified for each model variant.
• Dimensions are provided in millimeters, including length, width, height, and flange hole patterns.
• Disc coupling thickness is 4.8 mm with torque tightening specifications (48 kgf·m or 479 Nm).

Weight and Packaging

• Net weight (N.W.) and gross weight (G.W.) are listed for each model, ranging approximately from 850 kg to 1210 kg net weight.
• Package dimensions (LxWxH) are provided, generally around 1270x740x1080 mm to 1470x740x1090 mm.

Assembly and Mounting

• Details on AVR (Automatic Voltage Regulator) assembly positions with options for changing the position.
• Separable side plates with options for configurations with or without PMG (Permanent Magnet Generator).
• Drip-proof shutters plate is standard for marine use; non-marine use available on request.
• Shaft dimensions and mounting hole patterns (e.g., M20x40 tapped holes) are specified.

3. Standards and Model Identification

• Models are identified by codes SLG314C through SLG314G, with incremental changes in power and mechanical dimensions.
• SAE numbers and center of gravity (C of G) data are provided for each model to assist with installation and handling.
• Intertek certification and New Era SLG branding are noted.

4. Key Recommendations and Notes

• Use drip-proof shutters for marine applications to ensure protection against moisture.
• Torque specifications for disc coupling screws must be strictly followed to ensure mechanical integrity.
• AVR assembly position can be customized depending on installation requirements.
• Model selection should consider both electrical ratings and mechanical dimensions to ensure compatibility with system requirements.
