Composite Substation Post Insulator 33kv Electrical Silicone Insulators

Product Description

Composite Substation Post Insulator 33kv Electrical Silicone Insulators

Quick Detail: 

METO 33KV Electrical Silicone Insulators composite station post insulator

Application:

Introduction composite insulator is consist of insulation core, slilicon rubber sheds and end fittings at both terminals.
As the main structure, insulation core is made of epoxy resin, supporting housing, inside insulation and end fittings at both ends and withstanding mechanical load. The core has good tension strength usually over 600Mpa, which is 2 times than ordinary steel,5 to 8 times than ceramic material, at the same time, the core has good performance at dielectric property, erosion resistance, bending fatigue resistance, creepage resistance and impulse resistance. Silicon rubber sheds mainly protect the core, shield rain and snow, and widen the creepage distance and outside distance.
It's made of high molecular polymer silicon rubber, with fire retardant, inhibitor and coupling agent as auxiliaries, the high temperature and pressure vuicanized process provides good hydrophobicity, migratory aptitude, erosion resistance, aging resistance and electric insulation properties. When flashover occurs, it performs good at fracture resistance, distributing voltage averagely and has 2 times electric voltage than ceramic insulator at the same flashover situation.
Composite insulators provide by us is made of reinforced steel end fittings with maze design, multilayer protection and good sealing, which have solved the main problem of insulator that is interface electric puncture. Connection of core and fittings uses the most advanced coaxial constant pressure crimping technology, assisted by automatic sound control damage inspection system, assuring the reliability and stability of core and fittings connection. Using ERC high temperature acid-resist bar, surface of the core and silicon rubber is applied with specified coupling agent. The high temperature and pressure disposable molding inspection technology confirms all technical regulations meet domestic and international standards, making the housing and sheds the newest generation insulator unit in high voltage transmission line.

Technical Support

Technical support on pre-sales stage. DINGLI has own survey and engineering company with more than 100 engineers. We have special pre-sales engineer to work with customer at early stage of the project.

Site assistance

Site assistance in Latin American market, so far we have sales and service center in Spain, Chile, Bolivia, Peru, Ecuador, Senegal, which will make a fast response for customer.

Warehouse and Emergency Supply

Warehouse and emergency supply for spare parts, damage parts and missing parts: DINGLI has built production line in Quito and warehouse for transmission line and distribution network in Ecuador, Bolivia and Senegal with common use spare parts.

Design and Consultant

Supported by both domestic engineering company and Quito tower design center, could provide technical consultant and design service within our scope of work. For Quito tower design center, most of the engineers are local staffs. The Design is based on ASTM protocols meantime with GB material standard, which will reduce the weight, and avoid the replacement on the profiles to save the working time.
