KLDXF Cable Distribution Box

KLXDF Cable Distribution Box

The KLXDF low-voltage cable junction box is currently used primarily in power systems with three-phase AC 380/220 V, 50 Hz, and a rated current of 630 A or less—such as those found in urban residential communities, industrial zones, industrial and mining enterprises, and high-rise buildings—serving as a power protection enclosure for branch wiring in trunk-type cable networks and for the control and protection of branch circuits.
The KLXDF low-voltage cable junction box is manufactured using SMC (sheet molding compound) through a single high-temperature molding process. It features a low density, corrosion resistance, aging resistance, excellent sealing performance, safety, and an attractive appearance. With all-weather protection capabilities, it meets the demands of various harsh environments and locations in outdoor engineering projects, overcoming the shortcomings of outdoor metal cable junction boxes, such as susceptibility to rust, short service life, and poor thermal insulation. The SMC composite material used in this new type of cable junction box consists of unsaturated polyester resin as the matrix, glass fiber as the reinforcement, along with fillers, pigments, and additives. SMC material offers advantages such as high mechanical strength, light weight, corrosion resistance, long service life, high dielectric strength, arc resistance, and flame retardancy. Additionally, the product design is flexible and suitable for large-scale production.

Advantages & Features

1.Materials and Appearance—The enclosure is made of SMC composite material and is formed through a single high-temperature molding process. The surface is flat and smooth, with uniform color and high scratch resistance.
2. Excellent Sealing Performance, Safe and Reliable, User-Friendly—The enclosure can be configured with front or rear doors according to customer requirements, facilitating operation and maintenance. The doors feature a three-point locking mechanism with waterproof protection for the lock cylinder and are sealed using a pressure-fit recessed gasket, ensuring safety and reliability. The enclosure meets the IP65 rating requirements of GB4208, effectively preventing rainwater ingress and providing all-weather protection.
3. High mechanical strength and excellent flame retardancy—Constructed from SMC composite material, the enclosure is lightweight yet highly durable and offers excellent flame retardancy. The door features full-length longitudinal hinges that resist deformation and ensure good interchangeability during installation.
4. Corrosion resistance, aging resistance, and strong electrical insulation—The enclosure offers corrosion resistance, aging resistance, excellent high-voltage protection, and strong electrical insulation, making it suitable for various harsh environments.
5. High-Temperature Resistance and Anti-Condensation — Made from SMC composite material, this enclosure offers thermal insulation and heat retention properties unmatched by metal materials. It withstands high temperatures and effectively prevents moisture condensation. Mounting plates or live busbars can be installed directly onto the enclosure. Its unique and aesthetically pleasing design enhances the urban environment.
