| Composite Insulator |
The composite insulator line of XIYA includes line insulators comprised of line rod,line post, traction line type and line spacer, station insu-lators comprised of outdoor solid core, indoor solid core type, post and tension hollow post and tension rod, insulating bushing comprised of oil impregnated paper condenser wall bushing and dry type condenser wall bushing. Moreover , shed booster for station insulation, feeding rod for locomotive and dry type polymer current transformer are also available.
The shed housing polymer for XIYA composite insulator is prepared using specific composition mixing developed by XIYA experts for years, contributing the highest grade of tracking and corrosion resistance in conformance with IEC standard, which shows no apparent degra-dation after artificial accelerate ageing for 1000h and natural exposure test for 15years.
The XIYA insulator are manufactured with unique one - piece injection molding technique, excluding possibility of interface feakdown. Amain frouble which may destroy the normal operation of insulators. The unique gluing connection of line rod insulator with metal getting keeps FRP rod intact, providing the highest reliability of insulator in respect of its mechanical performance with practically no degradation even in environment of high temperature or severe cold.
The composite insulator, characteristic of small size, light weight, high mechanical strength, shatter-free, easy handling, well shock-resistance,pollution-resistance and minor maintenance, grows fast as a new generation of inslator.
Insulator with specific parameters other than those listed hereafter is required by customer, it can be supplied by technical agreement. If any insulator of other application is needed , XIYA is willing to proceed cooperative development to meet utmost the customer demand.

Insulator Quality Guarantee
Any products made by XIYA are according to the ISO9001 management system to ensurance the quality and service.
The Compaction and Interlinkage Technique
The compaction and interlinkage of end fittings adopt advanced acoustic emission detection control system which is used for spaceflight and avigation test, it's sensitive to distinguish several fiberglas' break, and has alarm equipment to make sure the veracity. And it has advanced coaxial isobarically technique , can conquer the labiliza - tion of the compaction and interlinkage.
Predominant umbrella cover characteristic
Excellent silicon directions for producing chemicals or metallurgical products, advanced
one-off moulding tech and secondary vulcanization, make the product much more advantage
than the conventional chinaware insulator.
Application
Protection of medium/ high voltage AC networks against both, multiple atmospheric and switching over voltages as well as Very Fast Transients (VFT). the protection Suitable for of transformers, transformers in arc furnace applications, cables,generators,parallel to capacitor banks,and railway vehicles.Can be used mechanically as support insulator or as suspension insulator in case of application as line arrester . For indoor and outdoor installation.
Keystone
The metal-oxide surge arrester (MOSA) is the most advanced over voltage protector in the word.Due to make the varistor of core com-ponent mainly adopt MOSA. Compared with the conventional silicone carbide arrester, this prescription of the product improves greatly the Voltage-Current(U-I)characteristic of the metal-oxide varistor and increased through-current capability at over- voltage so as to bring a radical-changes for the characteristic of the MOSA.
Under the circumstance of normal operating voltage, the current through the MOSA just on microampere degree. When suffered from over voltage,the MOSA's excellent non-linear characteristic will make the current through the MOSA increase to several thousand ampere,While the MOSA will be under the circulating state and release over voltage energy so as to protecting the power transmission equipments against the damage caused by the over voltage.
Usual service condition
a) Ambient air temperature within the range of -55ºC to +50ºC.
b) Altitude not exceeding 2000m.
c) Frequency of the A.C. Power supply not less than 48Hz and not exceeding 62Hz.
d) Power frequency voltage applied continuously between the terminals of the arrester not exceeding its continuous operating voltage.
e) Maximum wind speed not exceeding 35m/s.
f) Earthquake intensity not exceeding 7 degrees.
