Load testing device and insulating frame for load testing device

An insulating frame of a load testing device, wherein

• the insulating frame is disposed between a resistance unit and a cooling unit, the resistance unit having a resistor and a resistor holding frame that holds the resistor, and the cooling unit having a cooling fan,
• the insulating frame is coupled with the resistance unit,
• the insulating frame is coupled with the cooling unit, and
• the insulating frame covers a side surface of a flow path of cooling air from the cooling unit to the resistance unit between the cooling unit and the resistance unit.

A load testing device comprising:

• a first resistance unit having a first resistor and a first resistor holding frame that holds the first resistor;
• a second resistance unit that is disposed farther from the cooling unit than the first resistance unit is and that has a second resistor and a second resistor holding frame that holds the second resistor;
• a cooling unit having a cooling fan;
• and
• an insulating frame which includes at least one of a first insulating frame and a second insulating frame, the first insulating frame being coupled to the first resistance unit, being coupled to the cooling unit, covering a side surface of a flow path of cooling air from the cooling unit to the first resistance unit between the cooling unit and the first resistance unit, and the second insulating frame being coupled to the second resistance unit, being coupled to the first resistance unit, and covering a side surface of a flow path of cooling air from the first resistance unit to the second resistance unit between the first resistance unit and the second resistance unit.
