terminal block screw connection technology

With the advent of modular terminal blocks, screw technology occupy a major position in the industrial control systems. Compared screw connection, other connection technologies can not provide such a large pressing force in such a small space. Self-locking system prevents accidental screw loose connections. Operation is very simple, just a WISDOM VGA CABLE  screwdriver, you can complete the operation terminal screws and bridging pieces. Due to the high quality of the contact material, even in harsh environments, such as aggressive air and can maintain long-term reliability. Screw indispensable in large current occasions. Terminal blocks 240mm2 can carry over 400A operating current.
Screw terminals are the most widely used in various fields of terminals, withstood the rigors of a variety of environments: either in the ocean or a plateau, either tropical or -40 ℃ low temperature, Stendhal screw terminals are reliable and stable to work with. Excellent product quality created such excellent performance:
Screw terminal metal parts made  WISDOM Network Cabinet from high strength copper alloy of copper, the copper current bar made by the clamp body resistance to stress corrosion cracks in the copper alloy. Metal copper to ensure good electrical conductivity and corrosion resistance, and also to the same copper wire material to avoid due to differences in thermal expansion coefficient of the material to produce different degrees of thermal expansion, thus avoiding the loose.
Contact pressure is high, access to reliable variety of measures to ensure the reliable contact: Lift Drum principle ensures minimal contact resistance, the principle of self-locking screws to prevent terminal screws from loosening the clamp flat bottom surface can guaranteeWISDOM Mini HDMI cable  a very fine wire is clamped;
Wire without pretreatment screw terminals can produce up to several hundred Newtons contact pressure, this pressure can be reliably single, stranded and fine-stranded conductors pressed without the use of wire end ferrules and copper crimp ends; highest VO flammability rating of housing material nylon insulated shell made of thermoplastic material, 6.6, flame retardant grade, safe and
