Product Detail

Product Introduction

The Pole Fuse Switch Disconnector is a critical protective component designed specifically for low-voltage (LV) networks (typically up to 1kV). Mounted on poles in overhead or vertical distribution setups, it integrates switching, isolation, and fuse-based protection to safeguard LV networks from electrical faults. Its primary role is to interrupt overloads and short circuits, isolate faulty sections, and control power flow—ensuring the stability of residential, commercial, and light industrial LV grids while protecting conductors, transformers, and connected equipment.

Features

  • LV Network-Specific Protection:Optimized for low-voltage environments (≤1kV), it matches the current and voltage demands of LV networks, providing precise protection without over-engineering. Ideal for grids powering homes, offices, and small-scale industrial loads.

  • Triple Functionality:Combines three key roles: manual switching (to control circuit on/off), safe isolation (for maintenance, preventing electric shock), and fuse-triggered fault interruption (fuses melt to stop overloads/short circuits). Eliminates the need for separate components.

  • Pole-Mounted Design for LV Grid Compatibility:Engineered for pole installation, it fits seamlessly into overhead LV networks—common in suburban and rural areas. The compact, weather-resistant build minimizes space usage while withstanding outdoor conditions (rain, dust, temperature swings).

  • Rapid Fault Response:Fuses react instantly to abnormal currents, interrupting the circuit before damage spreads to other network components (e.g., distribution transformers, consumer meters). This limits downtime and reduces repair costs.

What is the difference between a dielectric and an insulator?
What is the difference between a dielectric and an insulator?
Dielectrics and insulators are distinguished primarily by their applications. One of the main differences is that a dielectric can store electrical energy by becoming polarized in an electric field, whereas an insulator resists the flow of electrons to prevent current conduction. Other key differences between them are outlined in the comparison chart below.Definition of DielectricA dielectric material is a type of insulator that contains few or no free electrons. When subjected to an electric fi

Fault Analysis and Treatment of Oil-Immersed Transformers
Oil Leakage at Welded JointsOil leakage at welded joints primarily stems from poor welding quality, such as incomplete or detached welds, and defects like pinholes and gas pores. Although oil-immersed transformers are initially coated with solder and paint during manufacturing, potentially masking these issues temporarily, the defects tend to surface during operation. Additionally, electromagnetic vibration can cause weld cracks, leading to oil leakage.To resolve such leaks, the first critical s

What losses occur during operation of the transformer? How to reduce losses?
Transformers experience various types of losses during operation, primarily categorized into two main types: copper losses and iron losses.Copper LossesCopper losses, also known as I²R losses, are caused by the electrical resistance of the transformer windings—typically made of copper. As current flows through the windings, energy is dissipated in the form of heat. These losses are proportional to the square of the load current (I²R), meaning they increase significantly with high

I. Methods for Cable Testing and Inspection:Insulation Resistance Test: Use an insulation resistance tester to measure the insulation resistance value of the cable. A high insulation resistance value indicates good insulation, while a low value may suggest insulation problems requiring further investigation.Voltage Withstand Test: Apply a high-voltage test using a high-voltage tester to verify whether the cable can withstand high voltage under its rated operating conditions.
