The important of using SWA is the grounding metal and the protection shield especailly when you lay under ground, as you didn't want if anything happen that will cause your to hack the car pouche to be hack.
Putting wires into PVC may open to other exploit like water leaking into it, qualities of the cable, etc.
Some time just not an good idea for cost saving for such thing. Hazard free...

http://en.wikipedia.org/wiki/Steel_wire_armoured_cable

armoured cable is not about lossless signal transmission at all.. It is meant to withstand outside weather and harsh condition like rain, hot noon temperature, cold night temperature, etc. For a normal cable, if it used outside the house, in long term, the cable condition (its insulation and its copper wire) will quickly deteriorate, become brittle, etc. It can lead short circuit, damaging the autogate, or even a fire..

If want to know pricing, ask contractor onsite to quote. Rough quote can vary from -30% up to 200% more. Have to survey the job need to be done. Is not buying tv , fridges or notebook.

Yes is possible, olden days contractor use double insulator and PVC tubes. But thos days the cables quality are very good, but if you want 7cores you may need to have two PVC pipe.

Using conventional single insulation cables is not design to be outdoor use, risk are higher. No doubt many developer use such method, to them after few years no longer their problem.

Armoured cables is preferred because it can withstand the element when buried underground. PVC pipe is also acceptable but you need to take into account soil settlement if your property is new and PVC pipe might crack under pressure and then your cable will be exposed, risking it being damage x yrs later then you need to spend money to replace it.

You want to lay on top of the concrete? Dont think its a good idea though.

Plus you will need a very large diameter of pipe to cover the cable. You can hack a channel along the side wall to your front gate then patch it over with cement.

Exposed or conceal?

Got budget use stainless steel pipe. Very nice if done properly.

If you are using dcmoto, you have option not to use incoming power from house by using solar. And that you don't need cabling.

Exposed or conceal?

some shop saying dcmoto 925w not recommended for gate larger than 18".. is it confirm? what are other option?

My contractor quoted me Dnor Autogate 712 model arms for my 16ft (4 folded) autogate RM1350 per pair.

Do you guys think it is expensive?

I dunno, but someone just give me such quotation.
so i wanna ask which one OK also.. so any idea?

How much this?
Looks like the box must install on the pillar one?

Can DC Mote 925W be force open if robber were to rob me at the car posh. 

Meaning this "feature" doesn't come with the product but depending on the installation? 

petlu28 & H2D Thank you for the clarification.

Yes, if the thief stand between the gate during its closing, the gate will stop AND sounded the alarm bro.. same with if your kid stand there, it will stop and sound the warning alarm too..

It is a very good thing to install that, imagine if you did not install the sensor, and your relative's car park between the gate during a visit, and suddenly you or your kid accidentally press the remote to close the gate. BANG! money goes out to repair the gate AND the car. 

Sent you the contact. Yes, I also contacted DCmoto directly before and quoted me rm1800 too. They also send my number to their authorised dealer to call me, but i never received a single call. So after that i contacted Mr Autogate.

if the controller box receive direct sunlight many hours a day... better do something to cover it....
it is just another generic plastic box same as others...

U know where is their location? KL?

Do they have showroom?
