Good fire-retardant performance, fire-proof grade 94V-0, European standard M1 fire-retardant grade, good fire resistance performance. Strong flexibility, can be bent at 180 degrees, damaged by non-strong external force, and the wire is not easy to break. Interlocking design, tight seal does not fall off. Strong temperature resistance, low temperature resistance of minus 20 degrees, high temperature resistance of 86 degrees. Arbitrary cutting holes are symmetrical, which is convenient for wiring. Complete specifications and durable. The insulated wiring trough cover can be replaced with a glue-containing non-slip wiring trough cover; after replacement, it can effectively increase the astringency and viscosity, so that the bottom of the wiring trough and the upper cover are tightly sealed to increase the tightness of the cover. A variety of specifications are available: coarse teeth, fine teeth, closed mouth, fully enclosed, keel, and weak current. It is mostly used in the robotics industry, new energy industry, building automation, industrial distribution boxes, transportation industry, high-voltage electricity, security inspection equipment, and medical equipment.
