Product Description

The DFW series high-voltage cable distribution box is a key piece of equipment for cable node connection in 35kV, 24kV, and 10kV power systems. It serves as a hub for collecting and distributing cables after they exit from switchgear. This product is designed for outdoor, maintenance-free operation, with a protection class of IP33, and can even be buried underground for flood resistance. It is widely used in urban industrial zones, residential areas, commercial centers, mines, steel plants, automotive, chemical, and cement industries, especially suitable for urban power grid transformation projects, significantly saving electrical equipment investment and improving power supply reliability.

Compact Structure & Easy Installation

The product has a compact design, small footprint, and is easy to install, operate, and maintain, requiring no routine maintenance.

Robust & Durable Casing

The casing is made of metal plates or stainless steel (2mm thick), with anti-corrosion design and special spray treatment, ensuring reliable operation in harsh environments for a lifespan of over 30 years.

All-Weather Outdoor Operation

It features a fully enclosed structure with full insulation, suitable for high temperatures, severe cold, flood immersion, and high dust areas.

Safe & Reliable Insulation

The high-voltage live parts are all made of silicone rubber and EPDM prefabricated cable connectors, ensuring personal safety with no exposed live parts.

Flexible Configuration

The flexible combination can achieve up to 7 outgoing branches. Combined with SF6 load switches, it can form a loop power supply. Cable joints allow live plugging and unplugging to break a load current of 200A.

Fault Detection & Cost-Effectiveness

Equipped with a fault indicator for quick circuit fault detection. One-time investment reduces cable length, saves floor space, and saves capital.

Frequently Asked Questions (FAQ)

What is the primary application of the DFW-12 cable distribution box?

It is designed for outdoor, maintenance-free cable node connection in 35kV, 24kV, and 10kV power systems, serving as a hub for collecting and distributing cables after they exit from switchgear. It is widely used in industrial zones, residential areas, commercial centers, and power grid transformations.

Does this high-voltage distribution box require regular maintenance?

No, it is designed for outdoor, maintenance-free operation. The high-voltage live parts are fully enclosed and insulated using silicone rubber and EPDM prefabricated cable connectors, requiring no routine maintenance.

What are the casing specifications and expected lifespan of the product?

The casing is made of 2mm thick steel plate or stainless steel with anti-corrosion and special spray treatments. It is designed to operate reliably in harsh environments for a lifespan of 30 years or more.

Can this distribution box handle harsh weather conditions or floods?

Yes. The equipment has a protection class of IP33 (IP30 for basic shell grade) and can even be buried underground for flood resistance. It is fully insulated and suited for high temperatures, severe cold, and high dust areas.

What are the configuration limits for outgoing branches and load current?

The system supports up to 7 outgoing branches. When combined with SF6 load switches, it can form a loop power supply. The cable joints can be plugged or unplugged live to break a load current of up to 200A.

Are samples available and what is the pricing?

Yes, samples are available (1 set minimum order). The sample price is negotiable and generally ranges from $1,800 to $2,500 per set (FOB Ningbo/Shanghai), depending on the configuration and voltage requirements.
