Type 275 Cable Description
Type 275 cable features a heavy-duty chlorosulfonated polyethylene (HD-CSP) outer sheath, exhibiting extremely low water absorption, ozone resistance, abrasion resistance, impact resistance, and compression resistance, while maintaining the required flexibility. To enhance mechanical protection without compromising flexibility, a layer of polyamide yarn is coated beneath the outer sheath.
This cable has a rated voltage of 1.1kV and is sometimes referred to as Type 275.1, where “.1” indicates the rated voltage of this series of cables. Its structure is 3+3+1, consisting of three non-independent shielded power conductors, three grounding conductors, and one retractable conductor, wound within a semi-conductive support and filler.
