HV Insulators, HV Bushings, Spacers & Dampers Report Ed 3 - 2017
HV insulators and bushings constitute one of the most importance components of electricity supply sys-tems. The failure of either an insulator or a bushing can cause catastrophic damage to equipment, injury and loss of life.
THE MARKETS FOR HV INSULATORS, HV BUSHINGS, SPACERS & DAMPERS
The report gives market sizes and predicts future market trends in value for each of the three product groups. The mar-kets for each product group are tabulated in $ value annually for a 5 year forecast period from 2016 to 2021, with the following analysis;
• Global totals, totals of 11 regions, national markets of 75 countries
END USE SEGMENT
The market for HV insulators is analysed by end use – transmission and distribution
• Global totals, totals of 11 regions, national markets of 75 countries
THE TECHNOLOGY
HV insulators are analysed by technology, material and core.
• With a global break by the materials—glass, ceramic and composite;
• With analysis by value for OIP (oil impregnated paper) and RIP (resin impregnated paper), globally, for every region and for each of 75 countries.
The OIP and RIP technologies are described, with advantages and disadvantages of each technology.
INSULATORS, SPACERS AND DAMPERS, TYPES AND APPLICATIONS
The many different variants of insulator, spacer and damper are described, with details of their applications and with plentiful illustrations. Transmission and distribution networks are discussed and applications of the products in the net-works reviewed.
VALUE CHAIN
The value chain for the electrical sector is analysed from the BOM (bill of materials) to the end market price, installed cost, and capex. Off-take of insulators and bushings operate at different levels in the value chain. This affects comparabil-ity of market demand for the two products.
MANUFACTURERS
The manufacturing landscape is discussed, and trends of globalisation pinpointed. Brief outlines of the 17 major manufac-turers are provided.
