Why some cable tray to spray, what is the role?
The difference is obvious, . the use of different materials: YC rubber cable insulation and sheathing materials are rubber insulation using IE4 rubber, jacket with SE3 rubber; and WDZNYJV insulation is used cross-linked polyethylene (XLPE), protection Sets of PVC (PVC) . the voltage level is not the same: YC-type cable rated voltage of 450 / 750V and below, while the WDZN-YJV-type cable rated voltage of 0.6 / 1KV and below. . the use of different occasions: YC cable use for a variety of electrical equipment such as: household appliances, electrical machinery, electrical equipment and equipment, mobile power lines. WDZN-YJC is used for combustion requirements are low halogen, or halogen-free flame retardant places, as a fixed laying transmission and distribution of energy. . the maximum long-term use of the conductor temperature is not the same: YC cable conductor maximum allowable operating temperature of 65 ℃, and WDZN-YJV cable conductor maximum allowable temperature of 90 °. In addition to the same cross-sectional conditions in the latter than the former carrying capacity to . the manufacturing process is not the same: YC cable manufacturing process is usually used in continuous steam vulcanization production, and WDZN-YJV is used in ordinary extrusion processing . the price Not the same: WDZN-YJV is much higher than the YC cable.
Each device on the USB cable requirements are not the same, your wireless network receiver on the signal quality and speed requirements are relatively high, it is recommended for a better line, or for a short first
YC rubber cable core is a soft strand, the outer jacket is a soft wear-resistant materials, suitable for tower machines and other equipment often used to move, WDZNYJV is halogen-free low smoke flame retardant, cross-linked polyethylene insulation, Ethylene sheathed copper core fixed laying cable, YC temperature is generally not more than 70 degrees, WDZNYJV temperature of 90 degrees and can withstand 750 degrees or 830 degrees high temperature combustion is not short circuit.
