How to choose the corresponding cable specifications for industrial box-type water chillers?

When selecting cable specifications suitable for air-cooled/water-cooled chillers, multiple factors need to be considered, including the cable's working current, working ambient temperature, cable laying method and environmental conditions.

1. Determine the working current: Determine the working current of the cable based on the power and usage of the chiller. Generally speaking, the operating current of a cable should not exceed 80% of its rated current.

2. Consider the working environment temperature of the chiller: the working temperature of the cable should not exceed its specified maximum allowable temperature. When working in a high-temperature environment, the life of the cable will be affected, so it is necessary to choose high-temperature resistant cables.

3. Consider the cable laying method and environmental conditions: If the cable needs to be laid in pipes, closed bridges, etc., you need to choose cables with better protective properties such as armored cables or rubber-sheathed cables. If the chiller cable needs to withstand greater mechanical pressure or vibration, corresponding reinforced cables need to be selected.

4. Consider economy: On the premise of meeting the usage requirements, the more economical chiller cable specifications should be selected as much as possible.

Based on the above factors, the following is a list of cable specifications that you can choose suitable for small and medium-sized box-type chillers.

It should be noted that cables of different specifications have different current carrying capacities and resistance values, and different countries use different voltage frequencies, so the selection needs to be based on the actual situation when using them. At the same time, in order to ensure the safe operation of cables, regular maintenance and inspections are required. For chillers with non-standard customized voltage and frequency specifications, you need to consult the manufacturer to select the corresponding cables.
