Product Name: 300kn Glass Shells for Transmission Lines Upto 500kv Model NO.: 300BP Brand: Hivolt Color: Light Green Certification: ISO9001 Size of Bearing Capacity: 300KN Connection Method: Trough Type Usage: High Voltage Power Transmission, Electrical Installation Type: B Type Insulator Structure: Suspension Insulator Material: Glass Application: High-voltage, Low-voltage Unit Spacing: 146mm Nominal Diameter: 255mm Creepage Distance: 320mm Coupling Size: 16b Trademark: Hivolt Transport Package: Wooden Pallet Specification: 3.8kg Origin: China Product Description We ,Dalian Hivolt Power System Co., Ltd.have supplied highquality glass insulatorsfor transmission lines up to 500kV for domesticNational Power Grid and overseas market due to high quality and competive price . we exported to UK, South Africa , South America , Ireland etc. If you are interested in this type of Insuators , please feel free to contact with us .Toughened Glass InsulatorsType : fog type & normal typeClass: up to 300 kN (E& M faliing load value)Standard: we can supply those insulators in IEC, ANSI , AU standards.we can design insulators according to customers requirements.Below is some data for 240kN insulator for example:Technical Specifications for U240BP toughened glassinsulator :Technical SpecificationUnitValue1Spacingmm1702Shed Diametermm3303Creepage Distancemm5504Mechanical Failing load StrengthKN2405Power Frequency Withstand VoltagedryKV90wetKV556Lightning Impulse Flashover VoltageKV1407Puncture VoltageKV1308Coupling Sizemm24HIVOLT toughened glass offers below features:High residual strength and no risk of line drop: Glass insulators can only existin two well defined conditions: intact or shattered.There is no intermediate cracked or puncturedstate. Therefore it is easy to quickly inspect strings , with no need foradditional test instruments, it will save more time and cost.Safety in construction Because of the impossibility of inducing hidden internaldamage, it is not possible to install a faulty string of glass insulators. so it skips routine test before transmission line constructions.Puncture resistance glass insulators resist the most extreme surgessuch as switching surges, steep front lightning strikes and power arcs. There can be no hiddenpuncture in a glass insulator.Environmental Considerations Complete recyclabilitytoughened glass insulators are made of fully recyclable components, so they do not represent a liability when retiring a line from service.Visual impact - toughened glass insulator easily blend with in the skyconsequently have minimal visual impact once installed on any linesApplications:Glass insulator U240BP works as a part of string insulator in transmission lines or substations up to 1000kV , the insulator can assembled as suspension string or tension string with related hardwares .the insulator string can be single V string , double V string etc.Competitive Advantage:The glass insulators has good advantage for example :mass production in auto- production lines , and insulation body of glass component are even and easy for quality control .the unqaulifed parts are recyclable, so it will save cost to provie more reasonable price for end users.Product quality are very reliable .insulator shell surface are very smooth and free of visual defect , and easy for maintance in high pollution areas . we offer very competitive price . High quality , best competitive is our goal .
