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.

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 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 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.

1. EXECUTIVE SUMMARY

Chapter 2 – HV INSULATORS, HV BUSHINGS, SPACERS AND DAMPERS
The four categories, insulators, bushings, spacers and dampers are defined. High voltage insulators and bushings are critical in electricity transportation. Although they are a relatively small cost within total manufacturing cost the consequences of failure are disproportionately large.

Chapter 3 – THE MARKET FOR HV INSULATORS BY TECHNOLOGY – OIP and RIP
The market for HV insulators is estimated for 2016 and projected to 2021, with country analysis.

Chapter 4 – THE MARKET FOR HV INSULATORS BY TECHNOLOGY – OIP and RIP
Oil-impregnated paper (OIP) and resin impregnated paper (RIP) are the two main technologies for high-voltage insulators and bushings. Usage and geographical penetration are analysed.

Chapter 5 – THE MARKET FOR HV INSULATORS BY END USERS
Usage is analysed by transmission and distribution.

Chapter 6 – THE MARKET FOR HV BUSHINGS
The market for HV bushings is estimated for 2016 and projected to 2021.

Chapter 7 – INSULATOR AND BUSHING TYPES BY SHARE
There are two main categories in considering the type of an insulator or bushing; the technology of the insulation and the material of the housing. Both fundamental qualities are outlined with the differences and options. The development of the technologies is outlined.

Chapter 8 – INSULATORS, TYPES AND CHARACTERISTICS
Insulators have both a mechanical and an electrical function. They must support the conductors and withstand both the normal operating voltage and surges due to switching and lightning. Insulators are broadly classified as either: pin-type/station/line post insulators, which support the conductor above or horizontal to the structure; or suspension type, where the conductor hangs below the structure. Insulators are usually made of wet-process porcelain or toughened glass, with increasing use of glass-reinforced polymer insulators.

Chapter 9 – THE MARKET FOR SPACERS AND DAMPERS AND OTHER COMPONENTS
The market for spacers and dampers is estimated for 2016 and projected to 2021.

Chapter 10 – INSULATOR AND BUSHING MANUFACTURERS
The number of manufacturers of high voltage insulators and bushings is on the increase but there are many more makers of small low voltage ones. The insulator and bushings industry started with small pioneering companies, often launched by engineers with visionary ambitions. These have been taken over by the electrical multinationals and now ABB, Siemens, Alstom and GE are leading the field with their subsidiaries. The leading companies are profiled.

Chapter 11 – THE VALUE CHAIN – FROM MATERIALS TO CAPEX
The cost of any product such as insulators and bushings, cable, transformers or circuit breakers can be
measured in a number of ways, from being a piece of unworked metal, to its final installation in working
order and finally as a constituent of total capital expenditure. Different price levels are important in this
supply chain, and the point of interest in the chain depends on the business to which the value is being
applied. Six points in the value chain are analysed, with mark-ups.

Chapter 12 – TRANSMISSION AND DISTRIBUTION LINE CONFIGURATIONS
The components which make up transmission and distribution networks vary in type and usage according
to circumstances. Each component is included to serve a specific purpose and that depends on the other
parts of the system. This section of the report outlines these components, their purpose and when they
are used.

Chapter 13 – CONDUCTORS
The number of conductors between towers or poles in a transmission or distribution network can
vary enormously. The minimum is one conductor, and at the other extreme the largest number
of conductors per span that we have encountered is a line which has no less than 36 conductors
between towers. This has an enormous effect on the numbers of insulators required in a network.

Chapter 14 – MOTION CONTROL, SPACERS AND DAMPERS
Bundle conductors consist of three or four conductors for each phase. The conductors are separated from
each other by means of spacers at regular intervals. There are many different types of spacer and various
functions.

Chapter 15 – DAMPERS, JUMPERS AND CLAMPS
A vibration damper is an energy dissipation device for removing the energy of vibration imparted
to a conductor by wind. Conductor vibration induces a relative motion between the clamp and
the inertia weights which causes flexure of the steel cable, resulting in dissipation of mechanical
energy by friction between the strands of the damper cable.

Chapter 15 – WORKING METHODS
Working on transmission lines is a hazardous occupation and a great deal of care must be
exercised if linemen are not to be electrocuted or fall from heights. Despite all precautions there
are fatalities every year. In general, there are four methods of live-line working which help
workers avoid the considerable hazards.
