Safety New Aluminum Journey | CZ Electric CZ1490 series explosion-proof distribution box- CZ Electric Co., Ltd

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 double explosion-proof gas dustSuitable 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 performanceIt 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;

Friendly design

Meet the complex and changeable conditions of the site

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 saves effort and is easy, and the installation and maintenance are 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, 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) Humanised internal structure design, avoid opening the cover to achieve side operation, save space to achieve 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 penetrates to every point, and the safety enhancing protective shell is matched to achieve multiple safety guarantees.

The latest standards:
Designed and manufactured according to the latest ATEX explosion-proof standards, the verification methods and test requirements are more streamlined and rigorous.

Accurate measurement:
Using the international third-party certification power dissipation method, scientific accounting of the highest surface temperature group of non-standard customized products, providing a more accurate, scientific and reasonable explosion-proof level, explosion-proof mark and explosion-proof ability matching, truly realizing the safety of customers.

A new level of security

Challenge 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:

1How 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 it is changing the component configuration scheme or optional customer products, you can obtain the real, safe and reliable temperature group through scientific calculation.

2. 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.

3. When the reference pressure measurement of flameproof products is carried out, it is determined by 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 analog partition test to solve the safety risk of pressure superposition (pressure increase) caused by built-in barrier.
