The market for HV insulators is estimated at $XX billion in 2015, rising by a cagr of 7.8% in nominal values to $XX million in 2020. The market for HV bushings at just under $XX million in 2015, rising by a cagr of 7.7% in nominal values to just under $XX billion in 2020. Although the HV bushing market is small it should be remembered that while insulators are sold to utilities and industrial users as an end product, bushings are sold to OEMs as a component in a manufactured product, principally transformers and circuit breakers. The global HV insulator market for transmission and distribution products has changed in recent years with the expansion of UHV lines and the need for huge insulators not previously envisaged. This report is concerned with the components in overhead networks. This section deals with spaces and dampers and also includes other components such as clamps, jumpers, ground wires and other smaller components. The market for spacers and dampers and other components is estimated at $XX billion in 2015, rising by a cagr of 8.2% in nominal values to $XXX billion in 2020. The five largest insulator manufacturers in the world account for more than 50% of the global market. These are ......
