Flat feeder introduction
The flat feeder is also called parallel feeder. It consists of two parallel wires. The two wires are fixed with insulating materials such as PVC or polyethylene. The feeders produced in China mainly include SBVD and SBYD. The former has a hard texture. The texture is softer, but the former is less expensive than the latter. Since the two wires of the parallel feeder are equal in capacitance to the ground, they are also called balanced or symmetric feeders.
