You can intuit T means Thermoplastic (insulation). I suggest that W means Wet no Wiring. Thermoplastic-insulated wire is rated 600 V and is designated as follows: TW — Indicates a single conductor having flame-retardant, moisture-resistant thermoplastic insulation. The wire is rated 60°C wet or dry.
