Proposal to replace the prohibition against the use of reinforced insulation for trolleybus circuits directly connected to the overhead power line with a requirement that such circuits shall be double insulated.
6. The expert from the Czech Republic introduced ECE/TRANS/WP.29/GRSG/2017/14 to improve the safety requirements for trolleybuses, particularly the double insulation of circuits directly connected to the overhead lines. GRSG adopted ECE/TRANS/WP.29/GRSG/2017/14 and requested the secretariat to submit it to WP.29 and AC.1 as draft Supplement 7 to the 06 series of amendments, as draft Supplement 6 to the 07 series of amendments and as part (see para. 5) of draft 08 series of amendments to UN Regulation No. 107 for consideration at their March 2018 sessions.
