4. Product features and advantages
, This product is a composite internal component.
The shell is made of glass fiber reinforced unsaturated polyester resin molded with beautiful appearance. It has excellent properties such as corrosion resistance, antistatic impact resistance and good thermal stability. It has better weather resistance and does not deform when used in low temperature environments.
The joint surface of the shell and the cover adopts a labyrinth seal structure. The sealing strip adopts a fully automatic linear glue integral molding and foaming process, combined with tight sealing, reliable protection, and good waterproof and dustproof capabilities.
The explosion-proof control switch has a compact structure, good reliability, small size, strong on-off ability, long life and a variety of functions that can be selected by the user. The explosion-proof structure adopts an independent explosion-proof arc extinguishing chamber with independent electrical contacts.
, Explosion-proof button (introduced from German technology) is compact in structure and light in operation. The button joint surface adopts a hyperbolic sealing structure and has strong waterproof performance. The button core adopts ultrasonic packaging technology to ensure reliable bonding strength and sealing performance. The button adopts a modular button. The functions of the two units can be freely combined. The button head has various methods such as self-resetting, mushroom type, gear selection type, and key parking.
The explosion-proof indicator light adopts a special exposed lamp head design (introduced from German technology), which can clearly observe the indication status from all aspects. It has complete rectification, voltage stabilization and filtering circuits. And the indicator light has high brightness D light source, low power consumption and long life.
The explosion-proof instrument adopts a special overload ammeter (voltmeter) with an overload multiple of up to three times the range, which the user can choose freely.
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.
, exposed fasteners and mounting feet are all made of stainless steel fasteners for anti-fall design and easy maintenance. Product color is black.
, Operation column installation method: column type, hanging type, bridge type or special. There are upper incoming cables, lower incoming cables or special incoming cables. The vertical pole used for column installation is hot-dip galvanized and sprayed with double anti-corrosion and cast iron chassis.
Both the cable inlet and cable inlet are equipped with explosion-proof cable sealing joints.
