Haichen supplies stainless steel junction box, tunnel bridge junction box, threading box, 0.5mm thick street lamp junction box manufacturer

Description :

　　At present, the junction boxes of elevated bridges are generally manufactured by bridge design units and on-site construction units, lacking consistent specifications. The manufacturing process is rough and prone to rusting; Due to human operation during installation, simple deviations may occur, such as the overall tilt of the junction box, inward sinking of the collision surface relative to the collision wall, etc., which can affect the appearance. In severe cases, it can lead to leakage of rainwater and dust from the junction box, corrosion of electrical components, and even the formation of short circuits. And the appearance scale and size of the junction boxes of different projects (different elevated bridges) are not consistent, which also affects the visual effect of urban elevated bridges to a certain extent. In addition, having bridge construction units manufacture junction boxes on site is not only time-consuming and inefficient, but also difficult to ensure quality. Wiring of sensor and wiring board: wiring shall be carried out according to the corresponding sensor number and the marking symbols on the circuit board. Wiring of sensor and wiring board shall be the same as that of conventional junction box. Wiring shall be carried out according to the corresponding sensor number and the marking symbols on the circuit board (the same as that of conventional junction box). The bridge junction box can be cast with ZL102 aluminum alloy, welded with high-strength corrosion resistant stainless steel plate, or welded with economical steel plate. The manufacturer of the bridge junction box can change the direction, quantity, terminal number, and nominal diameter of the inlet and outlet according to user requirements. Both steel pipe and cable wiring are acceptable, and cable wiring must be equipped with cable clamping and sealing joints. Product features of bridge junction box: 1. It can be used for connecting various electrical equipment in 380/220V and below circuits as a branch line and wiring. It can also be used as a connection for signal power supply in self-control or communication. 2. The shell is made of high-strength flame-retardant engineering plastic, which has a beautiful appearance and excellent functions such as anti-static, impact resistance, good thermal stability, and corrosion resistance. 3. There is a sealing ring between the cover and the shell, a bridge junction box, and it is fastened with stainless steel screws. 4. The terminal block can be selected as a pressure type or Phoenix's increased safety type dedicated terminal block. 5. The direction and quantity of terminal outlets, as well as the nominal diameter, can be freely changed. 6. Complies with the requirements of GB3836-2000 and IEC60079 standards. Installation and maintenance of bridge junction box: 1. Before installation, check whether the technical data on the nameplate matches the actual usage situation; 2. Check all fasteners for looseness, and tighten them if there is any looseness; 3. The internal and external grounding of the junction box must be outstanding and reliable.
