The Shrouds are made from high-grade polyvinyl chloride. The shrouds are used to increase the protection against external chemical and environmental agents of cable glands, especially on cable entrances. The significant reduction of dirt or foreign substances on the cable gland will facilitate the future maintenance of cable glands. The arrow end of the sleeves is readily cut with a knife, enabling it to be slipped over a wide range of cable diameters and assists ease of installation. Standard Shrouds are produced from black PVC. LSF shrouds are mostly used in grey colour but we also supply in white, red, and blue colour.
PVC is a very versatile and cost-effective material. Its main properties and benefits include:
1. Electrical Properties:
PVC is a good insulation material, thanks to its good dielectric strength.
2. Durability:
PVC is resistant to weathering, chemical rotting, corrosion, shock and abrasion. It is therefore the preferred choice for many long-life and outdoor products.
3. Flame Retardancy:
Because of its high chlorine content, PVC products are self-extinguishing. Its oxidation index is ≥45. Antimony trioxide has been used extensively, usually in combination with phosphate ester plasticizers, giving excellent fire performance and mechanical properties.
4. Cost/Performance Ratio:
PVC has good physical as well as mechanical properties and provides excellent cost-performance advantages. It has a long life span and needs low maintenance.
5. Mechanical Properties:
PVC is abrasion-resistant, lightweight and tough.
6. Chemical Resistance:
PVC is resistant to all inorganic chemicals. It has very good resistance against diluted acids, diluted alkalis and aliphatic hydrocarbons. Attacked by ketones; some grades swollen or attacked by chlorinated and aromatic hydrocarbons, esters, some aromatic ethers and amines, and nitro-compounds
