Wires & Cables www.siechem.com H.V. Generator AcceleratorChannel Deflecting Magnet Cable Polymer Cross-Linking Information Siechem Marine Power, Control & Data Transmission Cables Insulation & Sheath is energy electron beam irradiation cross linked from in house state of the art irradiation centre with prestigious AERB, (Govt. of India) Mumbai approval. The Insulation and Sheath materials are made of polyolefin co-polymer. Polyolefin consists of many random molecular chains, with no particular orientation, and no chemical bonds existing between chains before cross linking. After irradiation cross linking ( as shown in figure-1) the free & random molecular chains are cross linked as shown in the figure-2 Electron Beam Cross Linked Marine cables have higher Electrical, Mechanical, Thermal & Weathering properties. EBXL Siechem Marine cables have following special features. 1. Do not melt or flow even at very high temperatures. 2. High resistance against UV, Ozone & Hydrolysis. 3. Good flexibility, easy to strip 4. Improved abrasion/cut through 5. Better crush resistance 6. Solder iron resistance 7. Better over load characteristics 8. Resistance to stress cracking 9. Improved fluid, chemical & oil resistance 10.Slightly better flame resistance 11. Negligible change in thermal stability & electrical property 12. Improved fire resistance performance 13. Higher short circuit capacity 14. Improved high temperature mechanicals 15. High Degree of Cross-Linking and homogenity 16. No Polymer degradation due to high temperature as EB Cross-Linking occurs at room temperature 17. No oxidative degradation in polymers as observed in chemical cross-linking and so on.
