In the thick segment of the ascending loop of Henle 

Reabsorption of solutes is closely linked to the reabsorptive capability of the sodium-potassium ATPase pump, which maintains a low intracellular

sodium concentration.

In the thick ascending loop, 

Luminal membrane contains a three-ion cotransporter  known as Na+-K+-2Cl- cotransporter

#Unit 7. System Physiology – Animal

The energy for Na+-K+-2Cl- cotransporter is derived from the low intracellular Na+ gradient, which is maintained by the Na+-K+ ATPase

Thick ascending limb is called the diluting segment because NaCl is reabsorbed but water is not reabsorbed along with it.
