Company name: ACER HK s.r.o.
1. Protection of traction lines, equipment of trolleybuses, trams and electric locomotives in DC networks. 2. Protection of high-voltage transmission networks, transformers, switchgears, high-voltage cable lines and others in AC networks. 3. Protection from low-voltage overvoltage. Protection of electrical equipment, instruments, distribution transformer switchboards and others in AC networks.
1. PSP */10/III OVERVOLTAGE LIMITER – LINE DISCHARGE CLASS 3 PSP */10/III are limiters according to EN 50163 designed for the protection of converter stations and DC networks of electric traction systems linked to them from the effects of atmospheric and switching overvoltage. They are used for the protection of traction lines, electrical equipment of trolleybuses, trams, and electric locomotives.
2. PSP */10 kA OVERVOLTAGE LIMITER – LINE DISCHARGE CLASS 1 PSP */10 kA overvoltage limiters are designed for the protection of high-voltage transmission networks, transformers, motors, switching devices and high-voltage cable lines from the effects of atmospheric and switching overvoltage. The functional part of the surge arrester is made up of a column of varistors dimensioned for continuous operating voltage Uc, the outer shell is made of silicon rubber (in grey colour).
3. SPB */10 PP, AlFe or S SURGE ARRESTERS – PROTECTION OF LOW-VOLTAGE POWER NETWORKS The surge arrester with a rated discharge current of 10 kA and the maximum continuous operating voltage of up to 1 000 V is used for protection in low-voltage overhead distribution electric networks. SPB */10 AlFe – for bare outdoor lines. SPB */10 PP – for flat bus bars in switchboards. SPB */10 S – for insulated outdoor lines.
