Dowei Electric Porcelain Housing Arrester YW

Product catalog summary

General Description:

The Porcelain Housing Arrester complies with standards such as IEC 60099-4, ANSI/IEEE C62.11, and NEMA, and holds certifications including ISO 9001, KEMA, CESI, CE, TUV, UL, and ASTA.
It is designed to withstand seismic activities as per ETGI-1.020, IEEE Std 693, and NCh2369, and follows structural design standards like ASTM A325, ANSI/AISC 360, and AWS D1.1.
The arrester is capable of high altitude correction up to 5000m and provides instantaneous reaction to switching and lightning overvoltages.
It uses ZnO varistors with high discharge current and energy absorption capabilities.
Classifications include Station (SH-20kA, SM-10kA, SL-10kA) and Distribution (DH-10kA, DM-5kA, DL-2.5kA) with accessories like surge counters and leakage current meters.

Typical Specifications:

The document provides detailed specifications for 12~36kV and 52~362kV Porcelain Housing Surge Arresters, focusing on parameters such as highest system voltage, rated voltage, maximum continuous operating voltage, line discharge class, and long duration current.
Residual voltage values are given for various discharge currents and impulse durations, indicating the arrester's performance under different electrical stress conditions.

Key Data from Tables:

The tables list maximum residual voltages at different discharge currents (0.5 kA to 40 kA) and impulse durations (30/60µs and 8/20µs) for various system voltages, providing a comprehensive overview of the arrester's capabilities.
For example, a 36kV system with a 28.8kV rated voltage and a line discharge class of 2 has a maximum residual voltage of 70.7kV at a 0.5 kA discharge current and 118kV at a 40 kA discharge current.
