With their durable build and international safety approvals, the CZ0870n lights ensure long-lasting, stable operation even in the harshest conditions.

Integrated Design for Strength and Durability

One of the standout features of the CZ0870n street light is its integrated structural design. This design not only enhances mechanical strength but also improves overall reliability by reducing the number of external joints and potential leakage points. The integration contributes to better heat dissipation, longer lifespan, and stable performance during continuous outdoor operation. For industries requiring minimal downtime and maximum safety, the integrated design ensures dependable function around the clock.

Simple Installation and Maintenance

The product is engineered with user convenience in mind. The CZ0870n is extremely easy to mount, adjust, and maintain, making it a preferred choice for industrial and commercial facilities. Maintenance personnel can access internal components quickly, saving time during inspections or servicing. The straightforward mounting system reduces installation time, which is especially beneficial for large-scale outdoor setups such as refinery roads or chemical plant walkways.

Superior Protection with IP66 Rating

Environmental protection is one of the key criteria for outdoor explosion-proof lighting, and the CZ0870n excels with its IP66 ingress protection rating. This ensures complete protection against heavy dust, wind-driven rain, and strong water jets. In outdoor oil & gas fields, coastal areas, and dusty industrial environments, the IP66 rating guarantees stable and uninterrupted operation.

Whether exposed to sandstorms, chemical fumes, heavy rain, or extreme humidity, the CZ0870n remains resilient and secure, delivering dependable lighting performance.

Technical Specifications and Safety Certifications

Explosion-Proof Certification

The CZ0870n explosion-proof street light is certified under:

China CNEx: CNEx16.0845
Ex Mark:

Ex nR II C T3 Gc
Ex tD A21 IP66 T195°C

These certifications verify the light’s suitability for use in areas with explosive gas atmospheres and combustible dust environments. The “II C” gas group represents the highest level of gas hazard classification, meaning the light meets stringent global requirements for hazardous zones.

Application Zones

The CZ0870n is approved for use in:

Zone 2 (Gas Atmospheres) – Areas where explosive gases are not likely to occur under normal operation but may be present during abnormal conditions.
Zone 21 (Dust Atmospheres) – Areas where combustible dust clouds can form during normal operation.
Zone 22 – Areas where combustible dust clouds are infrequent but possible.

This wide application range makes the CZ0870n a versatile and dependable lighting solution for oil refineries, petrochemical facilities, tank storage yards, offshore platforms, grain processing plants, and manufacturing zones.

Temperature Ratings

Ambient temperature range: −40°C to +55°C
This broad temperature tolerance ensures stability in extreme environmental conditions—even during hot summers in the Middle East or cold winter nights.

Electrical Specifications

The CZ0870n supports multiple industrial voltage standards:

Rated Voltage:
- 220V AC
- 230V AC
- 240V AC
Frequency:
- 50Hz / 60Hz

This flexibility allows the light to be installed in facilities with different power infrastructures without requiring additional converters.

Terminal Specifications

L1, N terminals: 2 × 1.5–4mm²
PE terminal: 2 × 10mm²

The robust terminal capacity ensures strong, secure electrical connections suitable for industrial-grade wiring.

Performance and Reliability

High-Quality Light Output

While the specification highlights the structural and safety aspects, the CZ0870n also delivers excellent outdoor illumination, ensuring clear visibility on roads, pathways, and industrial work zones. This contributes to worker safety, operational efficiency, and reduced risk during nighttime operations.
