LT is the abbreviation for low temperature non-contaminating jacket, Type II, a jacket compound rated for flexibility and material compatibility in low-temperature conditions.
LT designates a low temperature, non-contaminating jacket compound of the Type II classification. Non-contaminating means the jacket will not transfer plasticizers or other constituents into adjacent insulation, which protects the insulation's properties over time. The low temperature rating indicates that the jacket remains flexible and serviceable in cold conditions rather than becoming brittle.
In commercial and industrial cable, an LT jacket is specified where cables must endure low temperatures without cracking and where compatibility between the jacket and the underlying insulation is important. Selecting the correct jacket designation helps ensure the cable performs reliably across the environmental range of its application. A jacket that stays flexible in the cold also resists the damage that handling can cause to brittle materials.
Jacket selection involves balancing properties, since a compound optimized for cold flexibility may differ from one chosen for abrasion or chemical resistance, so the LT designation signals that low-temperature performance was a priority in the formulation.
Matching the jacket to the environment in this way is part of building cable that performs dependably across its full service range.
At Windy City Wire, the focus on engineered low-voltage cable includes attention to jacket compounds like LT that match the demands of an application. Supplying cable with appropriate jacket characteristics helps ensure dependable performance where temperature and material compatibility are important considerations.
