HV Insulators, HV Bushings, Spacers & Dampers Report Ed 2 - 2016

HV Insulators, HV Bushings, Spacers & Dampers Report Ed 2 - 2016

HV insulators and bushings constitute one of the most importance components of electricity supply systems. The failure of either an insulator or a bushing can cause catastrophic damage to equipment, injury and loss of life. Together they have a global market size over $5 billion in 2016 and growing at 7.8% a year.

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 markets for each product group are tabulated in $ value annually for a 5 year forecast period from 2015 to 2020, with the following analy-sis;
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 networks 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 comparability of market demand for the two products.

MANUFACTURERS

The manufacturing landscape is discussed, and trends of globalisation pinpointed. Brief outlines of the 17 major manufacturers are provided.
