How to Verify Cover Thickness, Impact Resistance, and Heat Stability for the V22 Distribution Box

When evaluating the V22 series 12-way flush-mounted distribution box, the available specifications identify a PC cover, a 1.2 mm iron-sheet enclosure, and pure copper busbars and terminal bars. They do not provide a glass-thickness value, impact-resistance rating, or heat-stability test data. Buyers should therefore request model-specific technical documents and samples before approving the product.

Verification Priorities

• The stated 1.2 mm dimension applies to the iron sheet and must not be interpreted as the thickness of a glass cover.
• The supplied product information names PC as the cover material and does not confirm the use of glass.
• Request test reports covering impact resistance and heat stability for the exact V22 model and the materials included in the quotation.
• Inspect a physical sample and confirm that its construction, materials, and dimensions match the approved specification.
• The product is presented as an indoor consumer-unit distribution solution, while the company also identifies residential and commercial applications across its product portfolio.

Material and Performance Assessment

The V22 series is described as a 12-way flush-mounted distribution box. Its listed construction includes a PC cover, 1.2 mm iron sheet, and pure copper busbar and terminal bars. Since the supplied data does not mention a glass component or provide cover-thickness measurements, the glass-related requirements cannot be confirmed from the current specification.

During procurement, ask the supplier to identify the cover material for the quoted version and state how its thickness is measured. If impact or heat-stability performance is claimed, request the applicable test standard, test conditions, acceptance criteria, and complete results. All documentation should clearly reference the same model, revision, and material configuration as the supplied sample.

Quality Evidence and Project References

JUNON reports 100% production-line inspection, laboratory sampling and testing, and incoming inspection of raw materials as part of its quality-control process. The company also lists CE certification for switches and CB certification for 13A sockets. These credentials do not, by themselves, prove impact resistance or heat stability for the V22 distribution box.

JUNON's reported contractor projects include distribution-box supply for construction work in the Philippines, Kenya, and Ivory Coast. However, the available case descriptions do not include test evidence for cover impact performance or thermal stability. Product-specific documentation remains necessary for technical approval.

Frequently Asked Questions

Is the V22 distribution box supplied with a glass cover?

The available product description specifies a PC cover. It does not identify glass as the cover material, so this should be confirmed with the supplier if glass is required.

What does the 1.2 mm specification refer to?

The 1.2 mm dimension refers to the iron-sheet enclosure. It is not a stated measurement for the cover and should not be used as a glass-thickness value.

Can the supplied information confirm impact resistance and heat stability?

No. The provided data contains no relevant ratings or test results. Ask for reports covering the exact model and compare them with a production sample before final approval.

Conclusion and Purchasing Recommendation

For the V22 series, review the cover material and the 1.2 mm iron-sheet specification as separate items. Because impact-resistance and heat-stability performance are not stated, request product-specific test evidence and verify the results against the delivered sample. JUNON lists a minimum order quantity of 500 pieces and an estimated delivery period of 30–45 days. For technical assistance or solution details, contact Hayley Liao at hayley@junlang.com.
