4. Product features and advantages
This product is a composite product and the color is light cyan.
. The aluminum alloy grade of the cast aluminum alloy shell adopts advanced high-temperature one-time die-casting molding process. The die-cast product has a smooth surface and a dense metal structure. There are no bubbles and no trachoma inside the shell. It has good impact resistance. The explosion-proof performance of the product shell is significantly improved and the product has Permanent explosion-proof signs and trademarks made directly from molds.
In order to ensure that the aluminum alloy is resistant to strong corrosion, we have taken the following measures. We use surface shot blasting to clean the surface of the die-casting shell to better eliminate stress and enhance the adhesion of subsequent plastic spraying. , the industry took the lead in using electrophoresis technology to enhance anti-corrosion performance. , using domestic advanced high-voltage electrostatic spraying technology for surface spraying and advanced fully automatic drying line equipment, the plastic layer has uniform adhesion and strong adhesion. The anti-corrosion, anti-oxidation, and sunlight performance are significantly improved, which is much better than the traditional spraying process.
The explosion-proof transfer switch has a compact structure, strong on-off capability and long service life. The explosion-proof structure adopts an independent explosion-proof arc extinguishing chamber with each electrical contact being independent. The switch reset device is an independent structure with strong reset function. The switch has two handles, long and short. The long handle can have a locking function.
The explosion-proof button is made of high-strength reinforced % materials. The indicator lamp cover is made of materials imported from Germany and has good light transmittance. It adopts a small scattering spherical structure that can effectively scatter the light for easy observation.
. The explosion-proof button (introducing German technology) adopts ultrasonic packaging technology to ensure reliable combination of strength and explosion-proof performance. The button adopts a modular button function and can be freely combined with two units. The button head has various modes such as self-resetting mushroom type, select gear type with key parking, etc.
The explosion-proof indicator light adopts a special design (introducing German technology) and has complete rectification, voltage stabilization and filtering circuits, which is very convenient to use. And the indicator light is a high-brightness D light source with low power consumption and long life.
The explosion-proof instrument adopts a special overload ammeter. The overload multiple up to multiple times of the measuring range is freely selectable by the user.
The joint surface of the shell and the cover adopts a labyrinth seal structure, which has sufficient locking force and good waterproof and dustproof capabilities.
The internal wire connections of the operating column are all step-locking cylinder-type connection structures with firm crimping, anti-vibration and anti-loosening. The multi-stranded conductors should be connected to the terminals after crimping the tubular ends to ensure the stability of electrical performance. The color of the wires is completely in accordance with the national standard.
The installation method of the operating column is generally a column type, but it can also be made into a hanging type, a bridge type or a special one. Hanging installation can be made with top or bottom cable entry. The column installation is equipped with a vertical pole and a cast iron chassis.
Both the cable inlet and cable inlet are equipped with explosion-proof cable sealing joints. All exposed fasteners are stainless steel.
