Low Voltage Cables come in a variety of sizes, materials, and types, each particularly adapted to its uses. Cables consist of three major components: conductors, insulation, and protective outer sheath. The makeup of individual cables varies according to application.
Communications cable is essentially a cable used to transmit information by use of currents of various frequencies. In the basket of communication cables we offer; CCTV, Telephone Cables, CAT 6 UTP Cables, and Co-Axial Cables. These cables are typically used for data transmission, Ethernet connections, electronic circuits and networking
HomeCab-FR wires are ideal for domestic and commercial wiring, designed to handle up to 85°C operating temperature with in-house formulated flame-retardant PVC insulation. They are resistant to steam, boiling water, and have excellent electrical and mechanical properties.
Single & Multicore Flexible Copper Cable are used in low voltage signals, electrical motors, electrical appliances, control panels, DC power transformers, electrical boards, battery cables etc. These cables are highly flexible in construction & designed with high Di-electric strength.
Control cables encompass a large family of cables manufactured to various IS, BS, EN, VDE, and other international Standards. Our cables are designed for a wide range of application like industrial, signaling, transmission, measurement, control and regulation. These cables allow to transmit power at very low voltage to control the process or equipment.
SRP Engineering offers hot dip galvanized poles of octagonal cross section customized as per client requirement which can be used for illumination, power transmission & distribution and various other purposes. These poles are galvanized internally and externally after fabrication in accordance with IS-2629/ BSEN ISO 1461 or equivalent.
Tubular poles are used for illumination of streets, highways, play grounds etc. We have a technical team for installation and commissioning of tubular poles dimensions and technical specifications can be change as per customer requirement lets have some look on standard technical details of tubular poles on next three pages.

SOLAR CABLES / PV SOLAR CABLES
Introduction
PV Solar cables are designed for connecting photovoltaic power supply systems.They are dedicated to the photovoltaic system direct current (D.C.) side with a nominal D.C. voltage of a 1.5kV. These cables can be used indoor & outdoor for flexible and fixed installations with high mechanical strength in extreme weather conditions. cables are designed to withstand the demanding environmental conditions that arise in any fixed, mobile, roof or architecturally integrated photovoltaic installation
Applications
These cables are suitable for permanent outdoor long-term use, under variable and harsh climate conditions. They are designed and tested to operate at a normal maximum conductor temperature of 90°C and for 20,000 hours up to 120°C. Therefore, the expected per
