In high-risk industrial scenarios such as petrochemicals, gas plants, coal-chemicals and metallurgy, the safe operation of the electricity system is directly related to the safety of production and human life. As the core equipment for providing stable power to lighting systems, blast-proof lighting distribution tanks are not only a hub for power distribution, but also a key barrier against explosive accidents caused by electric sparks. In 2025, as the country continues to upgrade its safe production standards and further advance the intellectual transformation of “industry 4. 0”, the market placed greater demands on blast-proof lighting distribution tanks: not only the essential safety properties, but also the need for intelligent, customized and life-cycle services。
In this area of expertise, henanvalon electrical equipment limited has become one of the country's leading manufacturers of blast-proof electrical equipment, based on deep technological accumulation and continuous innovation. The introduction of 2025 specialized blast-proof lighting distribution tanks is becoming the preferred safety solution for many large energy enterprises with excellent performance and reliable quality。

I. Strict standards make the essence of security
Safety is the lifeline of blast-proof products. Walloon electric has always adhered to the r & d concept of “standards first, certified” and all blast-proof lighting distribution tanks strictly follow the latest national standards and international norms:
Gb3836. 12023 explosive environment part 1: general requirements
Gb3836. 22023 “equipment protected by “d” insulation shell”
Iec 60079 series of international standards
Gb500582014 design code for power devices for explosive hazardous environments
The product is certified by the national centre for the monitoring and inspection of the quality of explosive electrical products (nepsi) and obtained the " detonation certificate " , with blast markings covering the exdiibt4gb to exdiict6 levels, which can be widely applied to hazardous sites in sectors 1 and 2 where explosive gas mixtures of class iia, iib, iic are present, with the real realization of the "inner detonation, exterior detonation"。
It is fully dust-proof and resistant to powerful water-spray shocks, ensuring long-term stability in harsh conditions such as high outdoor temperatures, dampness and salt fog erosion。
Ii. High-quality materials, structurally sound and adapted to multiple conditions
In response to the special needs of different applications, hualong electric offers a variety of material options to comprehensively address complex environmental challenges:
High-intensity carbon steel: a combination of high-quality cold-rolled steel plates in q235 with acid-phosphorus + electrostatic spray coating on the surface, high tensile strength and high impact resistance applied to the general industrial environment。
Stainless steel: selecting 304 or 316 l stainless steel with excellent resistance to oxidation, alkalis and chlorine ion corrosive capacity, especially for powerful corrosive sites such as coastal refineries, offshore platforms, sewage treatment plants。
Aluminium high-pressure casting: in 2025, the new product uses a high-quality aluminium alloy high-pressure casting process of zl102, with a light quantitative design for the shell (with a weight of only 1/3) for steel products) and a high dispersive function, with excellent corrosive resistance and a well-detonated implosion interface, meeting the requirements of the gb3836. 2 standard to block the flame path。
Internal metaware have been selected with well-known brand breakers, contacts and leak protections, such as jung-tae, delisi and schneider, to ensure that circuit control is accurate, responsive and effectively perform multiple protection functions such as overloading, short circuits and leaks。

Highly customized services to achieve a “one-size-fits-all” approach
Walloon electric is aware of the uniqueness of each project. As a result, companies offer a full range of customized services:
Designed on a needs basis: depending on the drawings provided by the client or the actual work on the site, the box size, rerouting, mode of access and installation (walling, landing, embedding, etc.) may be tailored flexibly。
Intelligent integration: supporting the installation of remote monitoring modules, current voltage monitoring meters, rs485 communication interfaces, easy access to enterprise dcs, mes or wisdom monitoring platforms, and real-time data uploading and remote transport management。
Multi-species fit: complete solutions can be provided either by the conventional lighting system to supply electricity or in conjunction with the led blast light and emergency lighting system。
The need to diversify from ordinary plants to extreme weather regions is truly met by a “one-size-fits-all” approach。
Iv. Chain-wide service security, safe after sale
As a high-technology enterprise at the national level that combines r & d, production, marketing and servicing, hualong electric not only focuses on product quality, but also creates a better network of customer services. A network of technical services has been set up in various parts of the country, staffed by teams of professional engineers, which are available to clients:
Pre-sale technical support: programme design, product selection guidance
Installation of debugging assistance: on-site technical bottom-up and installation guidance
Post-maintenance maintenance: regular inspections, failure screening and rapid response。
From counselling to delivery, to long-term transport, walloon electric is always around the client and provides one-stop, life-cycle service support。
