Non-metal meter boxes (fiberglass reinforced meter box)

Non-metal meter boxes can be divided into two categories. The first category is plastic transparent meter boxes, and the second category is fiberglass meter boxes. Among them, fiberglass meter boxes include SMC and BMC meter boxes.

The non-metal meter box shell is a protective shell in the national grid facilities that leads to the meter measuring instruments of each household. Electric meters must be installed wherever electricity is needed. Therefore, the meter box shell is the protection device of the meter. Public facilities such as municipal administration, communities, telecommunications, electric power, rural power grids, factories, enterprises, agencies, heating, fire protection, etc. need to install electric meters and need electric meter boxes. Meter boxes are generally laid along a terminal from power facilities to households. Each household needs a meter box, that is, a set of meter box shells, so the usage is huge. Especially in recent years, the state has increased investment in power infrastructure and the development of urbanization. The state has invested heavily in public facilities, including rural power grid transformation, urban transformation and new wires and cables, and the transformation of iron-clad boxes into non-metallic meters. Boxes, etc., there is a huge demand for plastic meter boxes and fiberglass meter boxes.

Plastic meter box

The lid of the plastic meter box is made of imported weather-resistant polycarbonate (PC), and the bottom of the box is made of flame-retardant ABS and PC/ABS alloy engineering plastics. It can also be called a polycarbonate meter box. It has high insulation performance, high transparency, UV resistance, aging resistance, acid rain resistance, high temperature resistance, low temperature resistance, high impact strength, etc. It also has good rainproof, dustproof, ventilation, heat dissipation and other functions, and its normal service life is up to 20 years. years and above. The plastic meter box adopts an integrated design concept and consists of one, two, four, six, eight, ten, twelve, fourteen, sixteen meter boxes and a main control box. It can be installed and used in a single box, or multiple boxes can be assembled and used from the main control box. The main switch controls the installation of multiple boxes, and the entire metering circuit is integrated into an integrated closed box. Users can control it separately, making it easy to install and manage. It can also prevent electricity thieves from accessing the metering capacity and prevent electricity theft.

GL series meter box has beautiful design, smooth lines, clear and transparent box cover, reasonable layout of meters and electrical components inside the box, and can be installed with various types of electrical components, collectors, etc. The box cover is connected to the box with a three-way hook. There is a special sealing screw device in the lower and middle part of the box cover where the electric meter is located. The lower part of the box cover is fixed and interlocked with the box with sealing screws and padlocks. Only the power management personnel use special seals. A screw wrench and key are required to open it. The fully transparent box cover allows power management personnel to clearly read and directly observe various abnormal phenomena in the box in a timely manner. In this way, the hidden dangers of using electric clocks can be eliminated in advance and the management goal of "safe electricity use, prevention first" can be achieved.

Advantages of transparent plastic meter box:

The transparent meter box produced using this material has high insulation performance, good transparency, UV resistance, aging resistance, acid rain resistance, salt spray resistance, high temperature resistance, low temperature resistance, impact resistance, etc., and has good ventilation and rain protection. , heat dissipation and other functions, the normal service life is more than 30 years.

Adopting a transparent design, the transparent material is not only intuitive, but also can detect various abnormal phenomena in the meter box in time, eliminate potential safety hazards in electricity use in advance, and truly achieve the management goal of "safe electricity use, prevention first".

The pc transparent meter box adopts an integrated design concept and integrates various electric energy meters and the entire metering circuit into an integrated closed box. It not only takes up a small space and is easy to install and manage, but also prevents electricity thieves from accessing the metering device and prevents theft. electrical behavior.
FRP meter box

The raw materials of the two process methods of SMC (Sheet Molding Compound-sheet molding compound) and BMC (Bulk Molding Compound-bulk molding compound) are basically the same. They are both molding compounds prepared in advance from raw and auxiliary materials such as resin, glass fiber, and fillers. It is then molded or injection molded into a product. These two manufacturing processes originated in Germany in the 1960s and have developed into the main methods for large-scale and mechanized production of thermosetting FRP products in the United States, Western Europe, and Japan.

SMC meter box is made of SMC unsaturated polyester glass reinforced fiber molding. Its unique performance solves the shortcomings of wooden, steel and plastic meter boxes that are prone to aging, corrosion, poor insulation, poor cold resistance, poor flame retardancy and short lifespan. The excellent performance of fiberglass meter boxes has absolute sealing and waterproof performance. Anti-corrosion performance, anti-electricity theft performance, no need for grounding wire, beautiful appearance, safety protection with lock and lead seal, lifespan of more than 40 years outdoors and more than 60 years indoors, strength 1N.m, is the best choice for other metal plastics Meter boxes are unparalleled. The products are widely used in residential construction and civil electricity renovation. They can be installed with prepaid electronic meters and have a full range of meter box styles from 1 meter to 12 meters. There are more than 100 molds. They also have the features of being able to be installed in the meter box, with secondary protection and single-meter protection. It has multiple functions such as household switches, terminal blocks, and external control switches. It can be directly fixed on the wall or installed on a telephone pole to install mechanical or electronic watches DD862, DD282, etc. Install junction box, leakage switch DZ12, DZ18, DZ47, RCL fuse and isolation switch, etc. Users can operate the switch directly outside the box.

Features of fiberglass meter box:

(1) Adding a large amount of fillers to the formula, such as calcium carbonate and/or aluminum hydroxide, greatly reduces the cost, which is lower than the cost of raw materials for general FRP molding;

(2) The production efficiency is high. For example, molding an SMC chair surface takes only 7 minutes including auxiliary time and molding time; pressing a standard door surface takes 3 minutes; BMC injecting the reflective surface of a car headlight produces 2 pieces in half a minute; SMC molding with a diameter of 1.8 meters (weight of 36 kg) takes 6 minutes;

(3) High-quality products can be produced and can reach Class A surface;

(4) Complex products can be integrally formed, and inserts, holes, platforms, ribs, grooves, etc. can all be formed at the same time;

(5) Compared with ordinary thermoplastics, the products have higher heat resistance, insulation, elastic modulus and other properties;

(6) Closed molding, good production environment;

(7) High utilization rate of raw materials;

(8) The molding process is clear and concise, easy to implement mechanization and even automation, and does not require high proficiency of workers;

(9) The length and formula of glass fiber can be easily adjusted to adapt to products of different sizes and complexity requirements.
