Silicone-rubber Insulated Glass-yarn Braided Wire: SRGB
Max. operating temp:180℃
The SRGB and SRGB3 series offer glass-yarn braided wire that is mechanically stronger than silicone-rubber insulated wire.
The SRGB series offers products standardized by Ninomiya Electric Wire, with a rated voltage of 150 V or 300 V.
Applications
- SRGB series wire is used for applications such as wire used in general high-temperature parts with temperatures up to 180℃, and wire used for internal components of equipment.
* The standard identification color is white. We can also use black, red, green, yellow, brown, blue, gray, and other colors at your request.
* We can use nickel or other materials as the conductor at your request.
* We can also produce silicone-rubber insulated wire for sensors, multi-conductor products with more than two conductors, shielded wire, and more.
