Neon Sign GTO Wire BLACK SILICONE High Voltage Neon Transformer-Extra Thick READ.

This is Transco GTO-15 high voltage wire used in neon sign applications. This wire is very special at as as it is no longer made. For a short time, GTO-15 was made with a thicker silicone insulation for added safety but unfortunately, cost kept it from becoming a steady item to be found. The pictures I have added will show the difference in size of the black insulation compared to standard GTO-15 wire as well as GTO-10 wire. I will also include two electrode insulating caps that slide easily over this thicker wire and the electrode. These will come in 20 foot lengths (2-10’ runs) and the caps are grey. If you need more caps I can make a listing for that. I will have several wire lots for sale. The caps fit easily over 13 mm electrodes and smaller, and will fit over 15 mm electrodes with care.
