Dowei Electric Polymer Housing Arrester YHW
Dowei Electric Polymer Housing Arrester YHW
- The Polymer 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 can operate at high altitudes up to 5000m, reacting instantaneously to switching and lightning overvoltages.
- It features ZnO varistors for 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).
- Silicone rubber enhances chemical and physical resistance, UV resistance, and reduces flammability.
- Accessories include a surge counter and leakage current meter.
- The arrester is available in voltage ratings from 12kV to 362kV, with various line discharge classes and maximum continuous operating voltages.
- Residual voltage values are provided for different discharge currents and impulse durations, indicating performance under various electrical stress conditions.
