Three factors that affect the performance of ACSR conductors1. An ultraviolet (UV) and heat "Do no UV protection ACSR conductor for direct sunlight environment temperature ACSR conductor in a metal conduit or raceway is high, many polymeric materials in this temperature will reduce the use of life.
2. Water and mechanical damage (repair co...
Identifying counterfeit ACSR conductorsFake and low-quality ACSR conductor produces reap huge profits, regardless of the interests of consumers, the mass production of low-quality ACSR conductor products, the ACSR conductor market disrupts and damages the interests of the majority of users. So, how do identifying low ACSR cond...
Environmental requirements for cable layingToday's wire and cable are used to power transmission (magnetic) and can realize electromagnetic energy conversion, information, and wire products. Let's look at the wire and cable laying conditions.1. The ambient temperature. Because the weather temperature is variable, the environment tem...
Properties of silicone rubber and other standard rubbers1. Very soft, good elasticity, tasteless non-toxic, high temperature, and the characteristics of protection against the bitter cold. I am using a temperature range of 90 ~ 90 ℃. Silicone rubber is much better than ordinary heat resistance, can be continuous use under 200 ℃, and at 350 degrees ca...
Characteristics of PVC insulation material1. Manufacturing technology is mature, easy molding and processing and manufacturing. Compared to other classes of cable insulation materials, not only cost low but on wire rod surface, light color, printing, processing efficiency, hardness, adhesion, wire guide body itself both mechanical and physical p...
Difference between force cable and overhead cable1. The power cable covers an area of less. Generally buried in soil or lying indoors, the channel, the tunnel, and wire insulation distance is small, no tower covers an area of less, basically doesn't cover surface space. Aerial cable,overhead cables too.
2. Power cable, high reliab...
Causes of fiber attenuationCaused by fiber attenuation the main factors are: intrinsic, bending, extrusion, impurities, uneven docking, etc.
Intrinsic: is the inherent fiber loss, including Rayleigh scattering, intrinsic absorption, etc.
Bending: light in optical fiber bending part of the optical fiber may be lost due to scattering, causin...
Whether the 500kv overhead conductor outer bolts should be cold welded
1. Has a certain tension overhead wire alignment, the wire and lose fastening, spread the injury prevention wire and steel wire.
2. Pre-twist ring spacing should be consistent with the lead pitch adjustment. Die with the distance pre-twist ring should be appropriate.

The difference between power cables and cross-linked polyethylene cables
XLPE is an insulating material, cables used as insulation is XLPE cables, and power cables are insulated with cross-linked, cross-linked power cable. In addition to the cross-linked polyethylene insulation, as well as PVC, rubber cables are made of insulating materia...
A ground wire can be defined as "an element in a three-circuit system that gives excess electrical charge a safe way to escape the circuit". As its name suggests, a ground wire connects the circuit to the earth.The purpose of a ground wire is to protect a circuit from electric shock and possible fire. Outside the United States, grounding wires are often...
