Characteristics of outdoor and indoor disconnectors can be summarized as follows:

1. Post Insulator Design:
   Outdoor disconnectors use large-skirted insulators designed to withstand environmental conditions such as rain, dust, and pollution.

2. Current Breaking Capability:
   They are designed to interrupt small currents. Certain designs incorporate arc-extinguishing features to enhance safety and performance.

3. Ice-Breaking Mechanism:
   To ensure reliable operation under icy conditions, some disconnectors include mechanisms for breaking ice buildup during operation.

4. Grounding Switch for High Voltage:
   For higher voltage levels, grounding switches may be included to ensure circuit safety during maintenance or inspection. When the main switch of the disconnector opens, the grounding switch engages immediately for enhanced safety.

   

Outdoor disconnectors can be classified based on their insulation pillar structure into:

• Single-post scissor type
• Single-post telescopic type
• Double-post telescopic type
• Double-post enclosing type
• Three-post type

Additionally, V-shaped disconnectors are also available as a variant.
