Product Introduction

Features

◆SF6 Gas Insulation

Utilizes SF6 (Sulfur Hexafluoride) gas for superior arc-extinguishing and insulation, ensuring high safety and long service life.

Maintenance-free design with sealed construction, resistant to harsh environments.

◆Compact & Modular Design

Space-saving structure suitable for compact substations or overhead line applications.

Modular components allow flexible configurations (2-6 branches).

◆Load Switching & Protection

Equipped with SF6 load switch for safe load breaking and isolation.

Can be combined with fuses for overload and short-circuit protection.

◆Wide Applicability

Rated voltage: 12kV

Rated current: 630A (switch), up to 200A per branch.

Suitable for ring main units (RMU), cable branching, and distribution automation systems.

◆Safe & Reliable

IP65 protection rating for dust/water resistance.

Mechanical interlocks prevent misoperation.

Low operating noise and no flammable materials.

Conditions Of Use

(1) Altitude: The DFW10-12 cable branch box is within the correct operating range at an altitude of less than 2000m. Customers above 2000m can negotiate with the manufacturer to produce equipment to suit your special environment;

(2) Ambient temperature: The equipment can operate normally at -40~45 degrees. If your DFW10-12 cable branch box has an SF6 compliant switch inside, you need to pay attention to its ability to adapt to ambient temperatures of 15~45 degrees;

(3) Humidity: Under normal ambient temperatures, the daily average humidity is 95% and the monthly average is 90% or less. However, the ambient humidity varies according to the change in ambient temperature, so the actual humidity should be evaluated based on the temperature first;

(4) Earthquake intensity: The impact of earthquake intensity on the equipment is not strong at 8 degrees or below, but it will affect the operation of the equipment after exceeding 8 degrees;

(5) Wind speed: 35m/s or below;

(6) Remind each customer to try to use this product in an environment without severe vibration or other harmful gases.
