Release of joint box with internal wiring (SBJA series)

星和電機 星和電機
Hoshi and Electric Co., Ltd. has been supplying lighting fixtures for numerous roads and tunnels since 1957, when it delivered lighting equipment for the Kanmon Tunnel, the world's first underwater tunnel at the time. Road lighting fixtures are mounted on poles, which tend to accumulate moisture and can lead to condensation and water droplets. Our company offers a product that protects electrical wiring from moisture and water droplets, the pole-mounted junction box (SB series), which has a proven track record of over 40 years. We are now launching a new product, the "Junction Box with Internal Wiring for Poles" (SBJA series), which makes the internal wiring of road lighting fixtures safe and easy. The "Junction Box with Internal Wiring for Poles" (SBJA series) has a protection rating equivalent to IP68 for waterproofing and dustproofing, making it ideal for the humid environment inside poles. It comes with pre-wired connections, ensuring safety and ease of connection, as well as facilitating inspections. The junction box has a sealed compartment for the breaker and terminal blocks in some specifications, protecting the electrical wiring from moisture and water droplets that accumulate inside the pole. Additionally, the top cover can be opened to measure voltage and insulation resistance.
