Cable Kharidte Waqt Quality Kaise Check Karein: Dealer Aur Installer Ke Liye Guide

Cable ek aisa product hai jiski quality bahar se nahi dikhti. Do rolls bilkul ek jaise lagenge, daam mein 30% ka farak hoga, aur asli farak tab pata chalega jab installation ke 6 mahine baad problem shuru hogi — aur tab tak wo cable deewar ke andar ja chuki hogi.

Is guide mein wo cheezein hain jo aap order dene se pehle check kar sakte hain.

1. Printed Marking Padhein

Achhi cable ke jacket par jaankari printed hoti hai — aur ye sabse pehla filter hai. Dekhein ki ye cheezein likhi hain ya nahi:

Manufacturer ka naam ya brand
Conductor material (copper / CCA)
Cable type aur category (RG59, 3+1, CAT-6, fibre count)
Jis standard ke hisaab se bani hai
Length marking (meter numbers)

Jis cable par kuch bhi printed na ho, ya sirf ek generic naam ho, uske baare mein sawaal poochna zaroori hai. Marking manufacturer ki jawabdehi hai — jo likhta hai, wo claim karta hai.

2. Length Marking Ka Fayda

Jacket par har meter par number chhapa hota hai. Iska ek badhiya practical istemal hai: roll ki asli length check karna.

Market mein short-length rolls ek purani problem hai — 100 meter bol kar 90 meter dena. Length marking wali cable mein ye turant pakda jata hai. Roll ke dono sire ke numbers dekh lo, farak hi length hai.

3. Conductor Kaat Kar Dekhein

Sample ka ek sira kaat kar conductor ko dekho:

Pure copper — andar-bahar ek jaisa laal-bhura rang
CCA — bahar copper, andar safed/chandi jaisa aluminium

Blade se halke se khurach kar dekhna sabse aasan test hai. CCA mein upri parat hatte hi neeche se safed nikal aata hai.

CCA apne aap mein galat nahi hai — problem tab hai jab use copper bata kar becha jaye, ya jahan copper zaroori hai wahan laga diya jaye.

4. Gauge Aur Wazan

Conductor kitna mota hai, ye directly performance tay karta hai. Patla conductor matlab zyada resistance, zyada voltage drop, zyada heat.

Ek aasan practical check — same length ke rolls ka wazan compare karo. Copper bhaari hota hai. Agar do "same" rolls ke wazan mein bada farak hai, toh ya conductor patla hai ya material alag hai. Ye test lab ke bina hi bahut kuch bata deta hai.

5. Braiding Aur Shielding Dekhein

Coaxial cable mein braiding ki ghanapan (density) noise se bachaव karti hai. Patli ya kam braiding wali cable mein disturbance aata hai, khaas kar jab cable power lines ke paas se guzarti ho.

Jacket kaat kar braiding dekho — jitni ghani aur even, utna behtar. Jagah-jagah gap dikhe toh shielding kamzor hai.

6. Jacket Ki Quality

Modne par — jacket phatni nahi chahiye, chatakni nahi chahiye
Outdoor ke liye — UV resistant hona zaroori hai, warna dhoop mein 1-2 saal mein bhurbhura ho jayega
Smell — bahut tez plastic ki badbu aksar ghatiya recycled material ki nishani hoti hai
Motai even honi chahiye — kahin patli kahin moti jacket matlab kharab extrusion

7. BIS/ISI Aur Certification

Kai cable categories BIS ke dayre mein aati hain, aur unke liye ISI marking lagti hai. Agar aapka client ya tender certification maangta hai, toh:

Manufacturer se licence number maango, sirf logo nahi
BIS ki official website par licence number verify kar sakte ho
Test certificate/test report ki copy maango
Export ke liye jo standards chahiye wo alag hote hain — pehle confirm kar lo

Sirf packaging par logo chhap dena aasan hai. Licence number verify karna hi asli check hai.

8. Sample Pehle, Order Baad Mein

Ye sabse zaroori practice hai aur sabse kam follow hoti hai. Naye supplier se pehla order chhota rakho, ya sample mangwao. Sample par upar wale saare test kar lo. Ek baar supplier verify ho gaya toh har baar checking ki zarurat nahi rehti.

Aur ek baat — sample aur bulk supply same honi chahiye. Sample achha aur bulk alag, ye purani chaal hai. Isiliye bulk delivery aane par bhi ek roll check kar lena chahiye.

Manufacturer Se Direct Kharidne Ka Fayda

Beech ke traders se kharidne par do problem hoti hain: rate mein margin judta hai, aur quality ki jawabdehi dhundhli ho jati hai. Manufacturer se direct lene par:

Specification exactly likhwa sakte ho
Custom length, custom construction mangwa sakte ho
Koi problem aaye toh seedha wahi jawabdeh hai
Bulk par rate behtar milta hai

FAQ

Bina lab test ke quality kaise judge karein?

Upar diye gaye visual aur physical checks (marking, conductor cut, wazan, braiding, jacket) bahut kuch bata dete hain. Bade orders ya tender work ke liye manufacturer se test report maangna hi sahi tarika hai.

Sasti cable kabhi theek hoti hai?

Rate kam hona apne aap mein problem nahi hai — manufacturer se direct lene par rate waise hi kam hota hai. Problem tab hai jab kam rate specification kam karke aaya ho: patla conductor, CCA, kam braiding. Isliye rate compare karne se pehle specification match karo.

Dealer ke liye sabse bada risk kya hai?

Wapsi aur reputation. Cable install ho chuki hai, problem 6 mahine baad aayi, aur customer aapse hi poochega. Isiliye ek baar sahi supplier tay kar lena baar-baar sasta dhundhne se behtar hai.
