Why Does The Length Of The Pre-insulated Sleeve Need To Be Estimated And Cut To The Appropriate Length?

The estimated length should be based on the actual route on site, the reserved length at the pre insulated sleeve end, the number of fixing points, and the path through walls or beams. Although the design drawings indicate approximate dimensions, on-site deviations, wiring bends, and construction allowances may vary, so these variables must be considered when estimating the length. After measurement, a certain allowance should be reserved on pre insulated junction sleeve, and then the actual measured value should be subtracted from the allowance to cut it to a suitable length. This way, the cut insulated joint sleeve will avoid being excessively long and will not cause bending or compression risks.
