Insulators for the contact network of railways are designed to work in isolating nodes of the contact network of railways of AC voltage of 25kV. frequency up to 100Hz. and a direct current of 3 kV voltage, in an atmosphere with a different degree of contamination.
Code of the TN ЕАО ЕЭЭС: 8546
OKPD 2: 23.19.25.000; 126.96.36.199; 188.8.131.52; 184.108.40.206; 220.127.116.11
Components (units): The insulating part is made of ceramic electrotechnical material, as well as tempered glass. The insulators (end caps) are made of high-strength cast iron and have an anticorrosive zinc coating.
Normative documents: They must comply with the requirements of clauses 5b, 7, 12, 16, 24a, 24b, 24b of Article 4 of the technical regulations of the Customs Union TR TC 003/2011 “On the safety of the railway transport infrastructure”.
They are manufactured in accordance with the requirements of GOST 30284-2017 “Insulators for the contact network of railways. General specifications. “
Recommended certification schemes:
The cost of certification of insulators for the contact network of electrified railways consists of the cost of the main work for certification, as well as tests of selected samples of a certain type. And it depends on the certification scheme chosen by the applicant.
