        Ⅰ. Drilling fluid vibrating screen: weld switching box nearby, with a starting switch on the switching box, inlet wire is fence, and outlet wire is 25A four-core connector; power cable is 3×2.5 + 1×16 mm²; drilling fluid vibrating screen and switching box have reliable safety ground, and the grounding cable is 16 mm².

        Ⅱ. Drilling fluid cleaner: weld switching box near vacuum degasser, mud cleaner, screw pump and other low-power tank surface equipment, with a starting switch on the switching box, inlet wire is fence, and outlet wire is 25A four-core connector; power cable is 3×2.5 + 1×1.5 mm²; motor of the equipment and switching box have reliable safety ground, and the grounding cable is 16 mm².

        Ⅲ. Drilling fluid centrifuge: weld switching box nearby, with a starting switch on the switching box, inlet wire is fence, and outlet wire is 100A four-core connector; power cable is 3×25 + 1×16 mm²; motor of the drilling fluid centrifuge and switching box have reliable safety ground, the grounding cable is 16 mm² and the drill is 16mm².

        Ⅳ. Drilling fluid agitator: use magnetic starter to start, and the power cable is 3×6 + 1×4mm²; the drilling fluid agitator and magnetic starter have reliable safety ground.

        Ⅴ. Drilling fluid sand pump: (2 wieght pump, 1 shear pump) install motor switching box nearby, with the inlet wire of the switching box of 200A four-core connector and the outlet wire of fence; there is a remote starting switch on the switching box, a normally open contact and a normally closed contact; the inlet wire of controlling cable is 15A three-core connector; the power cable of drilling fluid sand pump is 3×50+1×25mm²; the drilling fluid sand pump and switching box have reliable safety ground. The grounding cable of the drilling fluid sand pump is 25mm² and the ground cable of the switching box is 16mm².

        Ⅵ. Mud tank: on the four corners of the tank are earth studs and obvious grounding marks. The whole fixation and control tank needs four earth electrodes, and ground connection between tanks should use cables of 1 x 185 mm².

        Ⅶ. Anti-explosion lamps: anti-explosion lamps are connected by connectors. The model of anti-explosion fluorescent lamps: BLD51-150/70 (Sino-US anti-explosion); the model of anti-explosion project lamps: BTL51-400(Sino-US anti-explosion); the lamp base should be welded on the tank surface, and the light pole type is detachable, which is easy to transport.
