What is Electric Meter Box?
Electric Meter Box
The main composition of the electric meter box is divided into ABS engineering plastic, polycarbonate transparent PC material, DMC, SMC four kinds of materials injection molding, pressing. In Europe and the United States and other developed countries, as early as a few decades ago this material has been widely used in the electrical field.
The scope of use of electric meter box in the public power grid cable branch box, low-voltage distribution box, water pump control box, communication device cabinet, street light and traffic light control box, multi-function metering box, integrated distribution box, capacitor compensation box, terminal box, wall mounted distribution box, metering box, etc is widely used.
Material characteristics
1.Electric Meter Box good electrical performance
Fiber-reinforced polyester materials used in the manufacture of electrical products have the following electrical properties:
Insulation resistance (immersed in water for 24h): 1.0x10Mω
Arc resistance: 180S
Leakage resistance mark index :≥ 600V
2.chemical corrosion resistance
Fiber reinforced polyester material has good corrosion resistance to acid, dilute alkali, salt, organic solvents, seawater and other characteristics, while metal material is not acid resistance, corrosion resistance to seawater.
3. lightweight high strength
Specific strength and specific modulus are one of the indicators to measure the bearing capacity of a material. The specific modulus of fiber reinforced polyester is similar to that of steel, but its specific strength can reach 4 times that of steel.
4. Good fatigue resistance
The tensile strength of fiber-reinforced polyester is slightly better than that of steel. The fatigue resistance limit of steel and most metal materials is 40%-50% of its tensile strength, while the fatigue resistance limit of fiber-reinforced composites is generally higher than this value, with the highest reaching 70%-80%.
5. Gap sensitivity
When the component is overloaded and a small number of fibers break, the load is rapidly distributed on the undamaged fibers to regain mechanical equilibrium. This is not comparable to metal components.
6.low thermal conductivity, small expansion coefficient
The thermal stress produced by the temperature difference is much smaller than that of the metal.
7. excellent ultraviolet resistance and anti-aging performance
Among nonmetallic materials, fiber reinforced polyester materials have excellent aging resistance. The anti-aging property test shows that the maximum aging thickness of the surface is less than 50μm in 20 years with different locations and climatic zones. The minimum thickness of most boxes is 5mm, less than 1% of the box thickness, so there is no obvious effect on the mechanical properties of the box. The company has adopted a special UV resistant surface treatment process to further strengthen its aging resistance.
8. long service life
The use history in Europe can prove that its service life is at least more than 20 years; The simulated aging test shows that its service life is more than 20 years, far more than the traditional materials such as metal. Some companies that produce tubing from such materials also claim a life of 50 years.
9. flame retardant, smokeless, non-toxic
This material is a kind of flame retardant material, flame retardant grade is FV0(non-metallic material is the highest), in high temperature burning smoke level is 15 (smoke level 1 -100), the smoke is non-toxic, toxicity level is ZA1(quasi safety level 1).
