9 big advantage analysis meter box

What is the meter box, meter box housing the main components can be divided into ABS plastic, polycarbonate transparent PC material, DMC, SMC four materials injection, repression. 9 big advantage analysis meter box, meter box so that people have a better understanding.

1, good electrical properties, used in the manufacture of electrical products, fiber-reinforced polyester material has the following electrical properties: insulation resistance (immersion 24h): 1.0x10 MΩ arc resistance: 180s Proof tracking index: ≥600v

Insulation protection and anti-creepage indicators in line with DIN / VDE standards. This material not only has excellent electrical insulation properties, and able to maintain good dielectric properties, immune to electromagnetic effects at high frequencies, does not reflect electromagnetic waves. These properties can be compared to the far non-metallic materials.

2, the meter box chemical resistant, fiber-reinforced polyester material with good acid corrosion properties, dilute alkali, salt, organic solvents, water, etc., while the metal material is not acid-resistant, corrosion resistant to seawater.

3, lightweight, high strength, specific strength and specific modulus material is a measure of carrying capacity indicators, specific modulus fiber-reinforced polyester material and a steel equivalent, but its specific strength up to 4 times that of steel before the.

4, good fatigue resistance meter box, the tensile strength of the fiber-reinforced polyester material slightly better than steel, steel and most metallic materials anti-fatigue limit is 40% -50% of its tensile strength, and fiber-reinforced composite anti-fatigue limit of the material is generally higher than this value, the maximum can reach 70% -80%.

5, notch sensitivity, the meter box and a small amount when the member overload fiber breakage, the load distribution on the rapid destruction of the fiber is not re-achieve mechanical equilibrium. This is the metal components can not be compared.

6, low thermal conductivity, thermal expansion coefficient, thermal stress generated when the temperature difference is smaller than the metal more. Technical Library content rich, comprehensive, Front reading!

7, excellent resistance to UV aging resistance, non-metallic materials, fiber-reinforced polyester material with excellent anti-aging properties. Meter box after aging performance tests show that the use of different locations, in which the different climatic zones, its surface thickness maximum age is 20 years less than 50μm. Most of the housing of the minimum thickness is 5mm, the thickness of the housing is less than 1%, so there is no significant effect on the mechanical properties of the cabinet. So outside the company took a special UV-resistant surface treatment process, more strengthened its anti-aging properties.

8, long life, the use of history in Europe can prove its life at least more than 20 years; after simulated aging tests show that more than 20 years of its life, far more than the metal and other traditional materials. Some use of such material pipe production company also claimed the life of the meter box which the pipe is 50 years.

9, fire, smoke-free, non-toxic, this material is a fire retardant material, flame retardant rating of FV0 (non-metallic material is most advanced), under the high temperature burning smoke emission level of 15 (fuming level 1 -100 level), non-toxic smoke, toxicity level ZA1 (quasi-security level).
