RS232—RS485 three-wire converter schematic

RS232 interface is a communication protocol used for short-distance (maximum 30-60 meters), slow speed, point-to-point communication, RS232-RS485 three-wire converter schematic diagram:

Porcelain Disc Insulators are typically used on high tension power transmission towers. Suspension Disc Insulator are widely apply for higher voltage that beyond 33KV to provide insulation due to its shirt surface construction design. Each unit has a single porcelain shell bonded to a steel cap (above) and a steel pin (below). Disc Insulator are designed to link together into strings, typically of two or more, to provide much higher voltage protection than any single insulator. Disc Type Insulator comply with the IEC, BS. As standards, the glaze color of the insulators are brown, light gray, blue, etc. The specified suspension insulators differing in diameter, unit spacing and creepage distance can also be provided, in addition, according to special requirements, these insulators can be provided wit zinc sleeve pins.

Features
1.Best for supporting conductors
2.Helps to maintain high voltage in high loads
3.Used in electrical wiring and cables for insulation]
4.Robust build
5.Corrosion less
