Solenoid valve cable
Thread Content
I would like to ask the experts: why are solenoid valves designed to use 1*2.5 cables, while the main cables are X*X*1.5 or X*X*1.0 cables? Confusion. Is it due to power consumption? Seeking help from experts
Solenoids generally have a separate 2*2.5 cable connected to them; according to the relationship between resistance and cross-sectional area, the larger the cross-sectional area, the lower the resistance. The power loss in the resistor is also smaller. Avoid situations where the solenoid valve cannot be driven. If the solenoid valve is located far away from the control room, a wire diameter of 2.5 is usually chosen. If the distance is short, a wire diameter of 1.5 is also acceptable
For 24V solenoids with low power consumption of around 4–8W, a 1.5 rating is sufficient; however, when the distance is significant, it’s better to use a 2.5 rating to prevent signal attenuation and reduce resistance
The thicker the wire core, the lower the resistance, and thus less power is consumed by the circuit
Generally, 2*2.5 mm shielded flexible cables are used for solenoid valves; after all, the larger the wire diameter, the lower the damping and the less loss there is.
