Product Introduction: CZ1490 Explosion-proof Distribution Box.
CZ1490 explosion-proof junction box (IIB+H, IIIC/Db), with EU ATEX explosion-proof certification, EAC Customs Union explosion-proof certification and China CCC certification, meets the latest international explosion-proof standards, and can achieve dual explosion-proof protection for both gas and dust. Suitable for potentially explosive hazard zones (Zone 1/2, Zone 21/22) and harsh working hazard areas. The shell is made of high-density aluminum alloy one-time molding (maximum size 750mm*750mm*480mm), and the surface protection adopts electrostatic spraying epoxy plastic powder process, and the sealing strip between the box body and the box cover can be optionally installed to achieve IP67 level protection, which has the characteristics of high protection level, good anti-corrosion performance, strong dustproof performance and excellent waterproof performance. It has the characteristics of high and low temperature resistance (-55°C≤Ta≤+60°C), and can easily cope with the complex and harsh environment of chemical sites, petroleum and petrochemical sites, and offshore platforms.
Excellent Performance, Fearless of Harsh Environments.
High and low temperature resistance: -55°C≤Ta≤+60°C;
Temperature group: maximum T6 (surface temperature does not exceed 85°C, which is the highest temperature class);
Dust and waterproof: IP66/IP67 (completely dustproof, resistant to heavy rain washing, resistant to 1 metre 30 seconds submersion in water);
Anti-corrosion grade: WF2 (the highest level of outdoor anti-corrosion);
Rated voltage: up to 1000V AC;
Rated current: up to 1250A;
Intelligent Design for Demanding Field Conditions.
Safer maintenance:
(1) The box body and lid can be hinged, and the opening angle of up to 100° allows a wider range of operation;
(2) It can also be equipped with CZ's self-developed automatic spring hinge; unscrew all the screws of the cover plate, and the hinge automatically spreads the cover plate, which is effortless and convenient, making installation and maintenance safer and more convenient.
More diverse specifications:
(1) Up to 11 standard product design specifications to meet the needs of different scenarios;
(2) The modular design realises the free combination between explosion-proof boxes and booster boxes, and flexibly adapts to solve the complex and changing conditions of the installation site.
Better design:
(1) According to the different characteristics of the components used, design the corresponding operation structure or Ex components (all ATEX / IECEx certification, safe and reliable) according to the needs of various electrical components;
(2) Ergonomic internal layout allows side operation without opening the cover, saving space and enabling double-layer component installation.
A New Level of Security, Multiple Certifications for One Product.
Comprehensive certification:
(1) Many explosion-proof certifications: It has a variety of mainstream explosion-proof certifications (EU ATEX, EAC Customs Union explosion-proof certification and China CCC certification);
(2) Complete component certification: the enclosure, mounting accessories, and internal components have obtained independent international explosion-proof certifications, and safety is built into every detail, with the safety-enhancing protective shell providing multiple layers of protection.
The latest standards:
Designed and manufactured according to the latest ATEX explosion-proof standards, ensuring the verification methods and test requirements are more streamlined and rigorous.
Accurate measurement:
Using the international third-party certification power dissipation method for accurate calculation of the maximum surface temperature class of non-standard customized products, providing a more precise, scientific, and reliable explosion-proof rating, marking, and capability match — truly safeguarding customer safety.
Meeting the Toughest Explosion Protection Standards, Challenging the toughest explosion protection tests.
According to the latest international explosion-proof standards, the authoritative certification body has put forward three difficult challenges for this series of products:
- How to solve the problem that the maximum surface temperature group of non-standard products is difficult to accurately measure?
Solution:
Use the power dissipation method to calculate the maximum surface temperature group of the product, whether changing the component configuration scheme or with optional customer products, you can obtain the real, safe and reliable temperature group through scientific calculation.
- How to solve the safety problems after opening holes such as different specifications of cable entry ports, quantity, etc.?
Solution:
Within the permissible opening sizes (M6 to M115 and NPT3/8 to NPT3) and hole spacing, the maximum area removal method is used to open the holes to meet the customer's various opening needs while ensuring the safety of the product.
- When the reference pressure measurement of flameproof products is carried out, it is determined by the empty shell, how to solve the safety risk of pressure superposition (pressure increase) caused by the built-in barrier?
Solution:
According to IEC60079-1:2014 standard, add an analog partition test to solve the safety risk of pressure superposition (pressure increase) caused by the built-in barrier.
