Ons gaan die skedule voor die beurtkrag na.

Because the verb here is nagaan, which is a separable verb in Afrikaans.

In a normal main clause, the first part of the verb goes into the usual verb position, and the particle moves to the end:

• Ons gaan ... na

So na is not functioning by itself as after here. It is part of the verb nagaan, which means something like check, review, or go over.

Here, gaan is part of the main verb nagaan.

That is an easy point to get confused about, because gaan can also mean go or can help form a future-like meaning in Afrikaans. But in this sentence, the clue is the na at the end. That shows we are dealing with nagaan, not the future construction.

Compare:

• Ons gaan die skedule voor die beurtkrag na.
  = We check / go over the schedule before the load shedding.

• Ons gaan die skedule voor die beurtkrag nagaan.
  = We are going to check the schedule before the load shedding.

So the position of na helps tell you what is happening.

Nagaan can mean check, review, go over, verify, or look through, depending on context.

With die skedule, the most natural idea is:

• go over the schedule
• check the schedule
• review the schedule

So it suggests looking at the schedule carefully, probably to confirm details or make sure everything is correct.

Because die is the definite article the in Afrikaans, and both nouns are definite:

• die skedule = the schedule
• die beurtkrag = the load shedding

Afrikaans uses die for singular and plural nouns, and it does not change for gender. So unlike some other languages, you do not have to learn different forms of the for masculine, feminine, or neuter nouns.

Here, voor die beurtkrag means before the load shedding.

The word voor can mean:

• before in time
• in front of in space

In this sentence, it is clearly about time, not location. So it tells us when the schedule is being checked.

Beurtkrag is the Afrikaans word commonly used for load shedding or scheduled power cuts.

It is a compound noun:

• beurt = turn / հերթ / shift / round
• krag = power / electricity

So the idea is roughly power cuts done in turns/rotations.

Afrikaans, like Dutch and German, often forms compound nouns as a single word. That is why beurtkrag is written as one word, not two.

The sentence follows normal Afrikaans main-clause word order:

• Ons = subject
• gaan = finite verb
• die skedule = object
• voor die beurtkrag = time expression
• na = separable verb particle

So the structure is roughly:

Subject + finite verb + object + adverbial phrase + separable particle

That final na is very typical of separable verbs in main clauses.

Yes. When the verb is not split, it appears as nagaan.

This happens especially when it is used as an infinitive, for example:

• Ons wil die skedule voor die beurtkrag nagaan.
  = We want to check the schedule before the load shedding.

It can also appear joined in clause types where the verb goes to the end.

So:

• main clause with finite separable verb: gaan ... na
• infinitive or certain end-position verb forms: nagaan

That is why learning separable verbs is so important in Afrikaans.
