What is the difference between a Kvvr cable and a VVR cable?
. in the housing construction, often to use the metal pipe, such as fire pipe, the basement of the line, the use of air defense engineering pipe and so on. . metal pipe with SC tube, galvanized pipe, etc., SC tube embedded in the concrete pipe wall need to do anti-corrosion (exposed, then the outside also anti-corrosion). . these metal pipe connections need welding and can not counterpart welding, but also to do cross-welding. . because the thick wall so the weight is also large, difficult to process, such as bending. . KBG tube is a galvanized thin-walled metal pipe, the thickness of the general in the 1.0-1.. it has a custom elbow, the connection method is the casing connection plus screw fixation. . SC pipe or galvanized pipe in the cost, the construction of the difficulty than the KBG tube is much greater. . based on the above, so now many housing construction are selected KBG tube instead of SC pipe and galvanized steel pipe. . the basement of the air defense project can not use KBG tube instead of metal pipe.
It depends on where to use, the general district with PVC pipe, office and medical fields such as magnetic field must KBG tube shielding. Iron pipe should pay attention to do a good job grounding
SC pipe, MT, TC tube, KBG, JDG are what pipe sc: welded steel pipe tc: wire tube thin steel pipe pc: hard plastic pipe ct: cable bridge cp: metal hose SR: steel trunking RC: water gas pipe sc Pipe is the steel pipe English word steelconduit the beginning of the acronym
. VVR cable for the polyacetylene insulation and external protective layer of soft copper cable, in front of K for the control cable. . the cable is usually a few or several groups of wires (at least two each group) twisted from the rope-like cable, each group of wires are insulated from each other, and often around a center twisted, the entire outer package Highly insulated cover. Cable with internal power, external insulation characteristics. . the cable has power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire cables, marine cables, mining cables, aluminum cables and so on. They are composed of single or multi-strand wire and insulation layer, used to connect the circuit, electrical appliances and so on.
