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 that time. Road lighting fixtures are mounted on poles, but these poles tend to accumulate moisture, leading 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 addition to our lineup, the "Junction Box with Internal Wiring for Poles" (SBJA series), which makes internal wiring for 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 moist environment inside poles. It comes with wiring for safe and easy connections, and inspections are straightforward. The junction box also features a sealed terminal block for the breaker and some specifications, protecting electrical wiring from moisture and water droplets that accumulate inside the pole. Additionally, the top cover can be opened for voltage and insulation resistance measurements.
