Are you sure? This looks like normal OHE panto. Highrise panto's are longer and have the 'HR' indicated on the panto itself.
Was there any marking on the loco indicating that it's for highrise OHE?

Sir, are high rise pantographs fit for 130/160 kmph operations ? I believe that due to longer length and different physique of the arm, the panto oscillations will increase drastically, hence restricting high speed operations.
Although this panto doesn't look like the regular stock pantograph fitted on WAP-5 locos.

The highrise pantos being developed are based on the WBL85 air-operated pantograph. The WBL85 is a air-operated panto, suitable for high speed operations as it is pneumatically operated and can maintain better control compared to the traditional spring operated pantos like AM12 or AM92 that are seen on most locos in IR.
The additional height does make it more susceptible to oscillations and adverse weather, but I believe, the panto itself will be able to sustain 130kmph (and probably 160kmph too, but that would need some confirmation) with no issues.
