Electrolytic copper is used as the transmission conductor inside the bus duct,which has high purity,high conductivity,low loss,and low heat generation,making it very suitable for industrial and mining enterprises that require high current load operation.However,the installation of the bus duct produced by Jinzhan Electric requires fixed installation,so it is only suitable for fixed field use,while traditional coal mine underground use silicone rubber frequency converter power cables.The bus duct is fixed,and although a single bus duct has no extensibility,remote transmission can be achieved through assembly and combination.

　　The bus duct has excellent electrical insulation performance,which remains stable even under temperature and frequency changes or moisture.In addition,it has good resistance to corona and arc,and the insulation layer can withstand 2-3 times the system peak voltage caused by high-order harmonic reflection in the frequency conversion system.Reduce noise,minimize misoperation,compact cable structure,can reduce the adverse effects of high harmonics in the output of the frequency converter,lower motor noise,provide overcurrent misoperation protection,and improve motor torque efficiency.To reduce energy loss,a traditional neutral wire is divided into three phases,which induce directional voltage and integrate the factors of potential imbalance to ensure the consistency of electric field phase,re balance the electric field,and reduce energy loss.Although the price of bus duct is low,the use of insulation film in the product ensures the stability and reliability of the overall equipment while reducing the volume of the compact structure.

　　Shielding is a better way to achieve electromagnetic compatibility and reduce electromagnetic radiation.By using copper wire loosely wrapped with copper tape to wrap the metal shield,the shielding surface area coverage reaches 100%,effectively cutting off the propagation path of electromagnetic noise formed by electrostatic coupling,inductive coupling or alternating electromagnetic field coupling in space,separating the grounding system of the two parts of the circuit,and cutting off the possibility of coupling through impedance.Silicone rubber has special surface self-lubricating properties and high flexibility,and works in harsh environments of high and low temperatures.The electrical and mechanical properties of cables are less affected by changes in bending radius and bending frequency.The acid and alkali resistance,corrosion resistance of silicone rubber are also good.It has good resistance to low concentrations of acid,alkali,and salt.For example,after soaking in 10%sulfuric acid at room temperature for 7 days,the volume and weight changes are less than 1%,and the tensile strength and elongation at break remain basically unchanged.

　　Like bus ducts,silicone rubber is harmless and odorless,making it an environmentally friendly material.The traditional bus duct shell is made of aluminum alloy material,which is lightweight,strong,and cost-effective.At the same time,it can greatly extend the service life of the bus duct.Many construction operations need to be completed outdoors,and in such an environment,there will inevitably be many corrosive substances,such as the corrosive nature of acidic components in rainwater.Therefore,when developing bus ducts,we need to consider these aspects together in order to provide corresponding performance guarantees for our actual use.
