Suspension insulator, generally by insulating parts (such as porcelain pieces) and metal accessories (such as steel legs, gossans, flange and so on) by the adhesive bonding or mechanical clamping and. The suspension insulators in power system is very wide application, belonging to the general external insulation, in atmospheric conditions. Overhead transmission line, power plant and substation bus and all kinds of electrical equipment external conductor must use the support insulator, and make the earth (or connected objects) or other potential difference of the conductor insulation.
The Product Structure
Product structure is composed of iron, glass and steel feet, and cemented into one. This product uses the international most advanced cylinder head structure, which is characterized by small head size. Light weight, high strength and large creepage distance. Metal materials can be saved and lower the cost of circuit. In order to meet the need for live working, on the brim with traditional domestic structure shape. Pollution prevention pillar insulator including ZSW-35/4 ZSW-35/400 ZSW-35/6 ZSW-35/600 ZSW-35/8 ZSW-35/800, cementing pillar insulator includes ZL-35/800F, ZLD-10F.Cementing pillar insulator including ZN-20/16, 30.Cementing pillar insulator including ZS-20/1000, ZS-20/1600, ZS-20/2000 cementing pillar insulator series include ZS-35/4, ZS-100110KV, ZS-220KV.Cementing pillar insulator series include ZSW-10, ZSW-20/1600, ZSW-35/6,8, ZSW-35/600-4, ZSW-35/800-4 cementing pillar insulator series pillar insulator synthetic rubber including HZDW-40.5Y40.5kV.Outdoor high pillar insulator synthetic rubber HFRS10-, ZA-6Y pillar insulator.
The Details of Polymer Insulators
Some enhancer in the promoter upstream, some located downstream, so the insulator effect does not depend on the insulator with the promoter of the relative position. Therefore, the reasons of the insulator effect direction are not really clear. It has been found two genes with trans activation effect of insulator function. Gene S2J (HW) encodes nuclear protein identification with its combination of insulators,polymer insulators only after the insulating effect. When the genetic mutation were inserted into the insulator, but lost the role of insulation in all tissues express. Another gene is mod (MDG 4), the gene mutation, its effect coincided with the Su (Hw) on the contrary, that these mutations are enhanced insulation effect, so that the insulator insulation effect will no longer have the directionality and expanded, is also blocked the upstream and downstream sides of the increasing effect of hadrons. One explanation is that the first Su (HW) DNA upon binding with insulator, the insulator has an insulating effect. Mod (MDG4) with Su (HW) combined with the insulator, losing insulation effect; mutations of the mod (MDG4) Su (Hw) cannot be the same as the combination, so the insulator and enhanced insulation effect.
