YH5(10)W-12 / YH5(10)W-12J Surge Arrester

YH5(10)W-12 / YH5(10)W-12J Surge Arrester

The surge arrester is assembled above overhead distribution transformers, where they shunt the energy from overvoltage events (especially lightning effects) to a ground connection and protect the equipment against damage in system.
Characteristic:
Voltage: 12kV
Current: 5kA / 10kA
Application: Overhead Distribution Line
Standard: IEC60099-4

Selection checklist

Prepare the Surge Arrester RFQ

State the system and arrester voltage. Include the nominal system voltage, arrester rated voltage and MCOV.
Confirm discharge duty. Specify nominal discharge current, required residual-voltage limits and the project duty cycle.
Define installation conditions. Include altitude, pollution level, maximum ambient temperature and mounting position.
Select hardware and accessories. Confirm brackets, line clamps, earth leads, disconnectors, bird guards, counters or monitors.
List document requirements. State the applicable standard edition, drawings, test evidence and acceptance documents required by the project.

Configuration and supply boundary

Review the YH5(10)W-12 / YH5(10)W-12J Configuration

The supplier table lists a polymer housing, Grade 304 stainless steel upper terminal and zinc oxide varistor options sized 35mm / 38mm /40mm / 42mm.

Electrical coordination

Confirm rated voltage, MCOV, nominal discharge current and residual-voltage limits against the project study.

Mounting hardware

State bracket pattern, terminal connection, line clamp and earth-lead requirements in the inquiry.

Failure indication

Confirm whether the supply should include a disconnector, insulating base, counter or monitor.

Commercial boundary

Quantity, packing, delivery schedule, test documents and destination requirements depend on quotation.
