Deyan Electric is a mature Yueqing-based electrical equipment manufacturer owning 10 professional production lines and a 50-member professional production and technical team. We independently develop and produce American Style Cable Junction Box for Power Distribution, a core medium-voltage power distribution hardware dedicated to solving cable termination, branching and line shunting problems for various power engineering projects. All products are manufactured in strict accordance with IEC international standards, with complete CE certification and standardized processing technology, ensuring stable, safe and long-term reliable operation in complex outdoor and industrial working scenarios.
Product Core Positioning
This equipment is a special medium-voltage power distribution device focusing on cable termination and branching work scenarios. It abandons the cumbersome wiring mode of traditional cable trenches, integrates centralized cable connection, shunting and protection functions, and is widely adapted to various municipal, industrial and new energy power projects. It fills the market demand for compact, safe and maintainable cable branching equipment.
1. Termination Function: Realizes standardized fixed termination of medium-voltage main cables, effectively fixes cable joints, avoids loose wiring and line displacement caused by external environmental vibration, and ensures the stability of main circuit power transmission.
2. Branching Function: Supports one-main-multiple-branch cable shunting, which can diverge the main grid power supply to multiple terminal power consumption units, meeting the multi-load power supply demand of power distribution systems.
3. Circuit Protection Function: Matches multiple functional module units to form a complete power distribution protection system, which can isolate faulty circuits in real time and prevent fault expansion within the power grid.
To sum up, American Style Cable Junction Box for Power Distribution serves as an indispensable intermediate transfer node in 10–15kV power distribution networks. It simplifies on-site construction procedures and greatly improves the overall safety of medium voltage cable networks.
Product Competitive Features
Deyan Electric optimizes every production procedure of American Style Cable Junction Box for Power Distribution. Combined with decades of medium voltage equipment manufacturing experience, this product possesses prominent advantages compared with other cable branch equipment available on the market.
1. Material Feature: The cabinet body adopts hot-dip galvanized steel plate plus secondary electrostatic anti-corrosion spraying. The unit can operate normally within -30°C ~ +50°C, with strong UV resistance and anti-rust capacity for outdoor environments.
2. Structural Feature: Single-side door design matched with horizontal multi-busbar layout. The cabinet width is reduced by 30% versus European cable branch boxes, which saves valuable space for compact urban secondary substation sites.
3. Connection Feature: Dual current grade design. The 600A main circuit uses bolt locking connection; the 200A branch circuit supports on-load hot plugging and facilitates daily power grid maintenance without complicated power cut operations.
4. Protection Feature: The whole unit reaches IP67 protection grade. It can withstand temporary water immersion and dense dust intrusion, suitable for coastal humid regions and mining sites with heavy pollution.
Each design feature targets real pain points encountered by overseas engineering contractors. The integrated design reduces additional construction costs and shortens the whole project implementation cycle.
