Moisture seepage and insulation failure are common safety hazards in power wiring and equipment connections. Volsun waterproof insulation tape, with high-performance synthetic rubber as the core, combines excellent waterproof sealing and strong insulation protection, becoming a reliable protection choice from low-voltage wires to high-voltage connectors.

What are the advantages of this waterproof insulation tape?

Adapting to the severe temperature difference of -40℃ to +85℃, the performance is consistent regardless of the severe cold outdoors or the high temperature in the equipment cabin, eliminating the sealing failure caused by sudden temperature changes.

The flexible design can tightly wrap multi-core cables, irregular joints and even valve surfaces to achieve all-round deep waterproofing. The water absorption is as low as 0.15% or less in 24 hours at 23℃, effectively isolating water vapor erosion.

The texture is flexible and can be cut at will, easily fitting various special-shaped structures. The paste is firm but clean without residue, no professional tools are required, significantly improving on-site efficiency and reducing material loss.

Its protection ability can withstand the test of strict standards:

• Excellent insulation performance: The insulation strength of the backing is as high as 20kV/mm or more (in accordance with GB/T1698), which can easily meet the insulation requirements of home wiring and industrial control lines and prevent short circuit risks;
• The volume resistivity exceeds 10¹⁴Ω·cm (in accordance with JB/T 1692), and the insulation performance is long-term stable, which is a reliable guarantee for the safe operation of high-voltage joints and grounding wires;
• The elongation at break of the adhesive layer exceeds 500%, and the high ductility ensures that special-shaped parts such as valves are tightly wrapped without gaps;
• The bonding strength with stainless steel plates reaches more than 26N/cm (in accordance with GB/T2792), and it is not easy to loosen after winding, which is particularly suitable for long-term moisture-proof sealing of outdoor cable joints.

Volsun waterproof insulation tape is an ideal companion for all kinds of electrical connections:

• Low-voltage wire insulation: Used for home wiring joints and weak-current line wrapping, its IP68 waterproof capability and 20kV/mm insulation strength can effectively prevent leakage in humid environments and ensure the safety of household electricity.

• High-voltage joint protection: Applied to key parts such as substation grounding wires, with high viscosity and extremely low water absorption, it can strongly block water vapor erosion and meet the stringent sealing requirements of high-voltage equipment.

• Special-shaped parts wrapping: Perfectly fit irregular surfaces such as valve interfaces and multi-conductor cable connection points. Its excellent formability can replace traditional complex sealing methods and greatly improve installation efficiency.

• Outdoor equipment wiring: Guard street light lines, outdoor distribution box connection points, etc., with a temperature resistance range of -40℃~+85℃, no fear of extreme weather, and significantly reduce the maintenance frequency of outdoor equipment.
