PROFESSIONAL LIGHTNINGPROTECTION, SAFE GUARDAGAINST DAMAGE

Lightning protection of buildings is a key issue of safe electric power & safety of electric appliances. Safe environment and reliable application of electric appliances directly relate to our personal safety and daily life, e.g. the overvoltage in our daily operation of household electrical appliances happens every day resulting in threat of power failure.

Lightning hazards to buildings and its electric appliances can cause various damages. The main causes can be thermal effect, mechanical force by lightning, lightning current invasion, electromagnetic induction etc. which bring about the damage on buildings and its electric equipment. Through years of our engineering experience against lightning, if there is no lightning protection measure, lightning strike may cause severe safety problems to people and property.

ZG provides most professional lightning protection solution to various buildings.
Our professional service guarantees you and your family to stay in a safe and comfortable living environment.
High quality living is guarded by our protection.

ZG LIGHTNING PROTECTION SOLUTION FOR BUILDINGS

ZG lightning protection solutions meet China standard GB 50057/ GB 50343-2012 (IEC 62305) which includes direct lightning protection, shielding, equipotential bonding, reasonable wiring, earthing, installation of surge protective devices etc. to build up a comprehensive lightning protection system. Installation of lightning protection system applies standard of NFPA 780. Ancient architecture applies China standard of GB 51017-2014 (IEC 62305).

Direct lightning protection: Choose ZG conventional lightning rod as direct protection against lightning and select type and post height based on calculation of rolling sphere method and set up protection ring belt of voltage sharing.

Earthing system: Choose ZG non-metal earthing module connected with natural earthing body of building to set up an integrated earthing grid.

Inductive lightning protection:

Install multi-stage surge protective devices in power distribution system and install multi-stage signal surge protective devices on signal lines to protect equipment concerned. Apply accordingly the shielding measures, reasonable wiring, equipotential bonding etc. to set up an integrated lightning protection system.

We provide the professional and safe measures to buildings against lightning through direct lightning protection, common earthing system and integrated measures against LEMP.

Our protection concept for buildings is based on common earthing, integrated measures and multistage discharge of over current & over voltage.

Class I SPD shall be installed at general distribution cabinet (LPZ0A or boundary between LPZ0B and LPZ1) or at connective interface between low voltage cable and overhead supply line. The SPD impulse discharge current Iimp generally shall be more than 12.5 kA for each protection mode and voltage protection level shall be less than 2.5 kV.

Decoupling device shall be installed between different class level SPDs when connective wire is <10 m between switch type SPD and voltage limiting type SPD as well as connective wire is <5 m between voltage limiting type SPDs.

The SPD has the tripping function and degradation display.

Signal SPD shall be installed at boundary of LPZ (LPZ0A or boundary between LPZ0B and LPZ1). Select single class SPD or coordinated SPDs based on amplitude of overvoltage, overcurrent and rated value of impulse voltage withstanding at equipment interface.

The selection of SPD shall match with the transmission rate, operational voltage and interface type. The SPD output port shall connect to equipment protected.

LIGHTNING PROTECTION FORDISTRIBUTED PHOTOVOLTAIC SYSTEM

Long-term, safe and efficient distribution of photovoltaic power generation system is ensured by the comprehensive lightning protection.

Enjoy your solar energy under safe protection.

SMART LIGHTNINGPROTECTION SYSTEM

The lightning monitoring system can monitor accurately on real-time the lightning current waveform, amplitude, polarity and time of the lightning current pass flow through the discharge passage.

PDUs and DCDUs are widely used based on the importance of equipment

distribution and power energy management in various data room systems.
