The order is for a range of different sizes and wattages, all customized to fit the specific hydraulic preheating systems of the client's mining excavators. The largest units are 24mm diameter by 600mm long, 240V, 2000W, while the smaller ones are 12.7mm diameter by 200mm long, 240V, 500W. All units are made from stainless steel 321, which offers excellent resistance to the vibration and impact that is common in mining equipment.
Our engineering team spent three months working with the client to develop the custom design, which includes a special reinforced lead wire connection that can withstand the constant vibration of the excavator without breaking. We also added a high-temperature silicone insulation sleeve over the cold zone to protect the lead wires from the heat of the hydraulic system, which can reach up to 120°C during operation.
