Low Voltage Cable Junction Box

Low Voltage Cable Junction Box is one of Cotenele's main products, The enclosure of the KDF1-Q-S low-voltage cable distribution box is manufactured from SMC composite material using high-temperature compression molding. It has the features of excellent impact resistance, flexural strength, aging resistance, abrasion resistance, corrosion resistance, aesthetic durability, and convenient installation. It also features high insulation strength, arc resistance, and high flame retardancy.

The enclosure fully meets the requirements of various harsh environments and locations in outdoor engineering projects. Inside the box, it can accommodate knife-type fuse switches, moulded case circuit breakers, bar switches (or fuse-switch disconnectors), busbar systems, etc. It is suitable for power transmission and distribution in public places such as urban and rural power grid renovation, municipal engineering, residential communities, high-rise buildings, etc., serving for the control and protection of dry-type cable branch circuits and feeder lines.

Main technical parameters

Working conditions

1. The ambient temperature shall not exceed +45°C and shall not be lower than -35°C, and the average temperature difference over 24 hours shall not be greater than 35°C.

2. The altitude of the installation site shall not exceed 2000m.

3. The relative humidity of the surrounding air shall not exceed 50% at a maximum temperature of +45°C. At lower temperatures, a higher relative humidity is permissible (e.g., 80% at +22°C). The possible effects of occasional condensation due to temperature changes shall be taken into account.

4. The equipment shall be installed in a location free from severe vibration and impact, and where the electrical components will not be subject to corrosion.

5. For use under special environmental conditions, the matter shall be resolved through consultation between the user and our company.

What are core functions of the low-voltage cable junction box?

The core functions of Low Voltage Cable Junction Box are as follows:

1. Cable Tapping/Spurring Function: Near the power load, distribution boxes can be used to divide large section main feeder cables into several smaller section cables, each supplying power to different users. This can avoid the waste of laying thick cables along the entire route.

2. Cable Transition/Connection Function: When the power transmission distance is long and the length of a single cable is insufficient, it is necessary to use a distribution box for relay connection. Compared to using multiple cable intermediate joints, using a distribution box for connections on lines over 1000 meters will make the system more reliable and safe.

What are the Product advangages?

1.Appearance: The enclosure of the Low Voltage Cable Junction Box has the features of refined and aesthetically pleasing, with small size, light weight, and easy installation, the external structure is compact and it meets creepage distance requirements.

2.Safty: The enclosure of the distribution box features high insulation resistance and high power-frequency dielectric strength. which offers a high safety factor and is the preferred product for power grid renovation.

3.Corrosion resistance: This cable junction box has excellent corrosion resistance, capable of withstanding corrosion from dilute acids, alkalis, and salts. It also exhibits strong resistance to various oils, organic solvents, and seawater.

4.Long-term Lifespan: This low-voltage distribution box offers outstanding aging resistance, with a service life of more than 30 years.

5.Sturdy and durable: This lv switchboard provides good impact resistance and machinability, and is not easily damaged.

6.Easy-stallation: The enclosure insulation of the low-voltage distribution box does not require grounding, which facilitates installation and saves significant manpower and material resources.

7.Lock: The box is equipped with dedicated insulating brackets inside, and a special lock (with a second padlock) on the door.

The products Structure and Components

1. Enclosure/Box: The enclosure is the outer protective structure. It must meet protection standards such as rain-proof, dust-proof, splash-proof ect, to ensure internal components are protected from adverse weather and environments.

2. Busbar System: Busbar System is the core internal component for collecting and distributing current whic is the typically copper busbars or conductors. This is the main channel for power distribution.

3. Switching and Protection Devices: Advanced distribution boxes are equipped with components such as disconnectors, fuses, or circuit breakers, these components is used for circuit control and protection against overload and short circuits.

4. Cable Connectors and Accessories: Accessories includes such as terminals, T-connectors, and other accessories for connecting incoming and outgoing cables. Openings at the bottom for cable entry/exit are fitted with sealing components to ensure the protection rating.

5. Grounding System: For ensure the safety of operator, the low-voltage distribution box includes an internal grounding busbar (PE bus). All metal parts that could become live must be reliably grounded.
