Precautions for parallel power supply of multiple cables - RIFENG CABLES- cable manufacturers in china rfcable.com.cnThe following precautions need to be taken into consideration when using multiple cables in parallel for power supply:1. Problems in parallel connection of cables:<1. When cables are connected in parallel, the parallel cables must have the same specifications and models, otherwise cables with small cross-sections or cables with large impedance will not Can pass the current corresponding to the corresponding cross-s... more

Rubber-sheathed cablesRubber-sheathed cables usually use Category 5 copper conductors as conductive cores. During their production and transportation, the copper conductors are often oxidized and discolored, which seriously affects the quality of the products. So how to effectively prevent the oxidation of rubber sheathed cable conductors?1. Choose high-quality copper rodsIn cable production, copper conductors are often purchased from outside. At this time, high-quality raw materials should be selected and the supplier's transportati... more

Electrical performance testingElectrical performance testing mainly includes conductor DC resistance testing, insulation resistance testing, and finished product voltage testing. 1. The DC resistance of the conductor reflects the electrical transmission performance of the cable, and directly affects the temperature, life, voltage drop, and operational safety of the cable during energized operation. Conductor resistance is mainly affected by the conductor material and cross-sectional area. If the purity of the conductor is low or the... more

Principles to be followed when cables are connected in parallel1. When operating space permits, the selection should be based on a single cable for power supply.2. If there is no suitable single cable for the temporary power supply project, the original cable can be used for parallel connection.3. When selecting cables for parallel operation, the specifications and models of the cables must be consistent. Parallel connection of cables of different specifications and models is likely to cause an accident due to excessive load current ... more

Two cold knowledge of plug First. The life-saving three millimeters on the triangular plug: Do people often complain that the three-wire plug occupies the space? It is not as convenient to use as the two-wire plug. I can’t wait to change the three-wire plug into a two-wire plug. In fact, one of the three-wire plugs is a grounding wire. The grounding wire is not a redundant design, but a "help" String". It is usually connected to the shell of electrical equipment. Once there is a leakage, most of the current flows to the earth from ... more
