HST Splice Calculator

Eurotech HST Splice Calculator
Use this worksheet to calculate the overall size of your splice and to estimate the best HST size.
Fill in Green Boxes Only
For a single-sided splice, use only the Side A column.
			Side A				Side B
			1.		2.		1.		2.
		Wire Lead	Wire OD		OD2		Wire OD		OD2
1. Fill in the OD of the wire insulator for each lead in your splice.		1			3.24				6.969600000000001
		2			4				0
2. Calculate the square of each OD.		3			0				0
		4			0				0
		5			0				0
		6			0				0
		7			0				0
		8			0				0
		9			0				0
		10			0				0
3. Add all numbers from column 2.			3.		7.24		3.		6.969600000000001
4. Multiply box 3 by 0.8. This is your Bundle Cross-Sectional Area			4.		5.792000000000001		4.		5.575680000000001
5. Take the square root of box 3. This is your Total Bundle Diameter			5.		2.6907248094147422		5.		2.64
			+10%		2.959797290356217		+10%		2.9040000000000004
			-10%		2.421652328473268		-10%		2.3760000000000003
Bundle Cross-Sectional Areas		It is recommended to design splices with cross sectional areas as balanced on each side of the splice as possible..
HST Selection by Bundle Diameters		Use the box 5 values to select the HST size from the Eurotech drawing.
Select IDe (expanded) that is larger than the largest side by at least +10%.		2.959797290356217
Select IDr (recovered) that is less than the smallest side by at least 10%.		2.3760000000000003
Divide the smaller box 5 by the larger box 5. Use this number to estimate the minimum required Shrink Ratio.		1.00 to 0.50 = 2:1 0.49 to 0.33 = 3:1 0.32 to 0.24 = 4:1 0.23 to 0.01 > 4:1					Use 2:1 ratio or higher	0.9811482730462595
