KS Series

The KS Series clamps use fibreglass-reinforced polyamide (non-metallic, UV-protected, flame-retardant, low-smoke/zero-halogen) and are designed for trefoil formation and stacked fastening of single- or multi-core cables both indoors and outdoors.    They accommodate cables with outer diameters roughly 22 mm to 46 mm.    The clamps are type-tested to IEC 61914 and withstand dynamic short-circuit forces up to 13,000 N, making them suitable even for installations subject to high electrical stress. 

They operate reliably from -60 °C to +120 °C (with short-term tolerance up to 220 °C), and their strength specs are ~120 N/mm² tensile and ~210 N/mm² flexural strength.    Because of the large contact area they exert low surface pressure on cables, helping avoid damage.    The KS Series is suitable for harsh environments — including UV exposure, ozone, oils, salts, alkalis, chemicals, and extreme climates — and installation is straightforward without special tools. 

If you like, I can also summarise the differences between KS and the other series (K, KT, KR) in a comparison paragraph so you can easily choose which clamp fits your need best.
