High-voltage isolating switches and load switches are two essential components in electrical distribution systems. Here is the classification, product descriptions, and applications of each:

1. High-Voltage Isolating Switches:
   Classification: High-voltage isolating switches are typically categorized based on their voltage ratings, current-carrying capacity, and operating mechanism (such as manual, motorized, or automatic).
   Product Description: High-voltage isolating switches are designed to provide isolation and disconnect power in high-voltage applications. They ensure the safe maintenance and operation of electrical equipment by physically separating the circuit from the power source.
   Applications: High-voltage isolating switches are commonly used in substations, power transmission lines, and other high-voltage electrical systems to isolate equipment for maintenance, repairs, or during emergencies.

2. Load Switches:
   Classification: Load switches can be classified based on their voltage and current ratings, interrupting capacity, and switching mechanism (such as air, oil, or SF6).
   Product Description: Load switches are used to connect or disconnect electrical loads from the power supply. They are capable of carrying rated currents and breaking or making load currents under normal operating conditions.
   Applications: Load switches are widely employed in distribution networks, industrial settings, and commercial installations to control the flow of electricity to various loads such as motors, transformers, and lighting systems.

These components play critical roles in ensuring the reliable and safe operation of electrical systems by providing isolation and control functions in high-voltage and low-voltage applications.
